The Effect Of Coloured Light On The Human Body
Artists and interior architects have long understood that colours can affect our feelings, emotions and mood. This is why the rooms in a hospital are often green – green calms and reduces stress. Other colours such as red, orange, yellow, blue, etc., have a different effect on the body. Chromotherapy, a.k.a. colour therapy studies these effects.
Chromotherapy or colour therapy is based on the premise that colours and light can be used to correct physical ailments. Depending on the location and nature of the ailment a specific colour may ease it.
One of the first scientists to consider the effect of colours was August Pleasonton. In 1876 he published ‘The Influence of the Blue Ray of Sunlight and of the Blue Color of the Sky’ in which he studied how blue can stimulate the growth of plants and cattle. He also mentioned that this colour can help make the human body better. This book introduced chromotherapy into modern medicine.
Colour therapy should not be confused with light therapy. In light therapy a person is exposed to a bright white light over a certain time. Light therapy is often used to treat skin diseases (more specifically psoriasis), sleep disorders and certain psychic problems.
Colours and their meaning
Studies have shown that people are able to distinguish approximately 10 million colours. These colours can be broken down into three primary colours: yellow, red and blue. Usually in chromotherapy, the secondary colours are added, more specifically orange, purple and green. Each of these colours has a certain meaning:
Red – The libido booster
Red is a warm colour linked to the kidneys, backbone and sense of smell. This colour gives more energy and is ideal for people who are often over-tired. Active people can use red light therapy to combat muscle and joint stiffness. And finally it also boosts sexual desires. Yellow – The depression killer
People with a difficult digestion can treat this with yellow light. This colour is associated with the stomach, liver and intestines. People with a depression could also benefit from yellow colour therapy. Blue – The bringer of peace
Blue is the counterpart of red. It can be used to lower high blood pressure or calm people down. Blue light can also help in the treatment of migraine. Your throat, ears and mouth are linked to this colour. Green – The strength provider
Green is the colour of nature. Green light therapy stimulates the creation of growth hormones and strengthens muscles, bones and other tissues. It can also boost your body’s immune system. Purple – The Nightcap
Purple light can help you fall asleep. It also reduces emotional and mental stress. The nervous system and eyes are linked with this secondary colour. Contrary to red light, purple light decreases sexual desires. Orange – The creativity source
Does your job demand a lot of creativity? Then orange can help. Orange stimulates the creative thought process and helps you come up with new ideas. This colour is linked to breathing. Breastfeeding women could benefit from orange light because it stimulates the production of breast milk. Coloured lighting cannot only create a certain atmosphere, it also affects our body.
Correctional Facility LED Lighting
Correctional facilities place a high priority on safety, security, and operational efficiency. LED lighting systems, can help meet or exceed performance standards in all three of these areas. Due to the instant-on and dimming capabilities of LED systems, new control methods are now practical and promise to allow even greater performance.
In Stockholm, AF Lighting has designed a media facade that reflects the weather, and helps build the brand of a major insurance company.
The head office of Swedish insurance company If sits directly above a busy motorway just north of Stockholm. It has always been an imposing building – but rather an anonymous one, with an unlit facade. ÅF Lighting was asked to do something about that.
The resulting solution is characterized by a soft, welcoming light, which matches the recently updated visual guidelines of the insurance company, and its concept of being “close to the people”.
For many years, the one distinguishing feature of the building was an old digital clock sitting on top of it, which also displays outside temperature, as a service to passers-by. ÅF Lighting kept this in mind when creating the lighting concept, which involves LED strips being fitted to the entire facade, with a dynamic light flowing through them like changes in the weather. The lighting scheme also reflects actual local weather conditions, enabling the public to experience the façade lit according to natural conditions such as wind, snow, rain, sun and clouds as well as the seasonal changes. The work also included to update the old clock with a new design and new media logo.
Apart from conveying a message about the weather, the lighting also gives the building a lighter, more dynamic feel, and provides an aesthetic experience for car-borne commuters on an otherwise eventless motorway.
”The project has presented challenges to which we have found innovative solutions”, says lighting designer Francesco Guastella. ”As part of the creative process, we worked closely with the customer to develop mood boards, inspired by their brand message about closeness to people. Eventually we decided that nature and its changes is something that everybody can relate to. Who has not gazed into the flames of an open fire, for instance, or at the waves lapping at a shore? This is what inspired us when creating the lighting programme that now flows along the facade.”
Installing the light rods proved to be the most challenging part of the project. As the façade faces a motorway, building cranes could not reach to all the necessary installation areas. Instead, climbers were hired to perform the work.
”It looked absolutely terrifying, but the results are extraordinary”, says an evidently pleased Francesco Guastella.
Now commuters are met by a beautiful façade each day, reflecting the weather in that particular moment. In other words, the lighting helps communicate the If brand, and adds value to people in their everyday lives.

115 Batman Street, Melbourne, Australia
The Base Building solution for 115 Batman Street was designed to meet with the Green Star requirements of the project. The overall building design utilizes an integrated design ideology, taking significant advantage of the available daylight via both the high and extensive glazing.
Window screening is used to provide amelioration of direct sunlight where necessary and the lighting control system that manages the lighting throughout the tenancy is linked to photo electric cells to dim the luminaires in relation to the available daylight. Motion sensors are also provided throughout to manage the lighting after hours by activating the lighting in areas of movement.
The fitout orientated spaces including the main reception, meeting rooms were designed with large luminous grids of pendants while the staff breakout space was designed to be deliberately different with custom pendants that feature panoramic photo montages of the Royal Botanical Gardens.

39 Victoria Street, London, United Kingdom
The refurbishment of this key building in Victoria involved the relighting of the main office floors with low energy lighting and the creation of an impressive new entry experience.
A special canopy feature was developed with integrated lighting built-in to visually link the interior spaces to the external streetscape. A series of canter-lever arms extend through the interior lobby and are brought together to form a canopy at the entry point on the streetscape. Adjustable lighting offers the facility for varying coloured presentations. Whilst a set colour balance is used at most times in a static mode, for special occasions the colours, tone and brightness can be set to different levels.
The lighting controls utilise the DMX protocol which in this project is on a wireless network, due to the complex nature of the building and the tight voids which precluded traditional cable ways to be threaded through the structure.

On October 13, 2016, Boston mayor, Martin J. Walsh unveiled the new LED-based architectural lighting of Boston City Hall. The lighting debut was during this year’s final Beer Garden on the Bricks event, themed “Light Bright Beer Garden.” The city intends the new LED lighting to highlight and enhance the building’s original design and increase public safety. The exterior lighting installation is one among several ongoing initiatives to highlight City Hall and City Hall Plaza and make them more inviting for residents.
“I am proud that for the first time in its 48 year history, Boston City Hall is going to shine,” said Mayor Walsh. “This state of the art lighting system will help make City Hall the civic heart of our city by livening up the plaza, while making the area safer and connecting us to Faneuil Hall and Quincy Market. Bringing new light to City Hall is symbolic of a more responsive vision here at City Hall, one that is meant to be engaging, inspiring, and serve as a beacon of the city and our values.”
New LED fixtures replaced the original Metal Halide exterior recessed lighting and the existing floodlights that illuminate the building’s lower levels and accentuate the entrances. The new fixtures cover the building in a warm white light, and they can produce a broad range of colors. Such color options can allow the City to light the building to acknowledge a variety of celebratory and public events.
The mayor lit the building blue to recognize the police officers injured in East Boston, and as a further demonstration of its light changing capability, the mayor changed the color to pink in honor of Breast Cancer Awareness Month. The pink lights at city hall added to pink lighting of numerous buildings and landmarks around the city.
The lighting highlights the original three-part design of City Hall. The lower levels house the public spaces of the building. The symbolic spaces including the middle sections hold the offices of the Mayor and the City Council, and the administrative spaces crown the building and house the administrative functions of government.
According to the city, the new exterior lighting improves security lighting. The city says that the system allows for the floodlights and associated conduit added to the building over the years to be entirely removed.
“By illuminating its iconic and bold form, City Hall’s interaction with Boston’s urban fabric may be reinvigorated,” said David Eisen FAIA, Boston Society of Architects/AIA (BSA) Vice President for Communications. “It’s a decisive step toward transforming one of the most internationally renowned buildings that make up our distinct architectural heritage.”
The new fixtures are more energy efficient than the Metal Halide fixtures and the existing Flood Lights that they replace. The LED lighting is expected to save the city about 300,000 kWh of electricity annually compared to the replaced lights. The LED technology has a projected 20-year lifespan compared to the 4-year life of the metal halide lights that the LED system replaces. The City expects additional savings from the cost of maintenance and light replacement.
Arcade lights have also been retrofitted with LED lighting to complement the new City Hall lighting. The same controller will be able to operate and coordinate both the arcade lights and the City Hall lights.
“It is wonderful that the City is taking this opportunity to recreate its own home place – City Hall – as the keystone and central event in an ongoing pursuit of improved illumination for our city,” said Todd Lee, President of LIGHT Boston.

An appreciative whoop went up from the crowd gathered Thursday night as the switch was flipped on the latest light installation by San Antonio artist Bill FitzGibbons.
From a vantage point on the 21st floor of the Frost Bank Tower, members of the arts community and city officials watched as “Kinetic Skyline” illuminated the Bank of America Plaza with a display of blue and green light.
“I’m really over the moon about this project because with this tremendous support from the owners of the building we were able to realize one of the largest light sculptures in the state of Texas,” FitzGibbons said.
Located at 300 Convent Street near the Tobin Center for the Performing Arts, the 28-story Bank of America Plaza is one of the tallest buildings downtown.
“It’s got all these stair step bays that go up along the side of the building, and so I thought that that would be really an interesting approach to go in there and emphasize those bays, which you visually can’t really see from a distance,” FitzGibbons said earlier.
Created with computerized LED lights, the effect of the installation is of a series of eight columns climbing up facades on the north and south sides of the building. FitzGibbons also created programs for holiday displays. Thursday night, he demonstrated the schemes for the Fourth of July and Fiesta.
The Bank of America Plaza is owned by Houston-based Griffin Partners and New York-based Clarion Partners. It is currently undergoing capital improvements.
“The building has had exterior lighting on it, I guess, since it was built,” said Lee Moreland, executive vice president of Griffin Partners. “It’s basically a dull, amber-colored lighting that we knew would need to be replaced, but not until the introduction to Bill did we contemplate that it could be something much more.”
FitzGibbons has created several light-based public artworks around the country. In San Antonio, they include “Centro Chroma Tower” at VIA’s Centro Plaza; “San Antonio Colorline” at the University Health Center-Downtown Brady Green Clinic; “Light Channels,” beneath the underpasses at Commerce and Houston streets; and “Day Star Archway” at the San Antonio International Airport.
He has received videos of bands performing and photos taken at the underpasses transformed by the installations.
“To me, that’s the magic and power of public art,” he said. “You can see that throughout the city where you go in and you do a public art piece like the Sebastian piece down by the Alamo or (Donald) Lipski’s internally lit fish hanging from the underpass on the Museum Reach or the George Schroeder sculptural wall that’s at the county courthouse downtown,” FitzGibbons said. “These projects really enliven our built environment and create a magic that contributes to the quality of life of urban living.”
