Colour for learning

We are six billion people living in a color-drenched world.  Researchers believe that there are between one million and seven million colors that the human eye can distinguish.  According to Berlin and Kay’s linguistic study, eleven basic color terms that fall into three classes are listed:

Black, gray, white (achromatic color terms)

Red, green, blue, yellow (primary color terms)

Brown, orange, purple, pink (secondary color terms)

Obviously people distinguish between different hues of colour. 

Color in the learning environment provides an unthreatening environment that improves visual processing, reduces stress, and challenges brain development through visual stimulation/relationships and pattern seeking. Visual stimulation actually rewires the brain, making stronger connections while fostering visual thinking, problem solving, and creativity (Simmons, 1995).  Colour should be incorporated to promote brain activity, but using more than six colours can be a distractor in classrooms, and strains the mind’s cognitive abilities.

Faily (1979) reported findings that optical stimulation by the use of warm colors and brilliance of lighting will cause increases in muscular tensions, respiration rate, heart action, blood pressure and brain activity. Cool colors and dim lighting bring about reverse effects such as muscles relaxing more and sleep being facilitated.

Yellow: 

Yellow (and the yellow family of colors) gets your attention faster than any other color. People notice yellow objects first.

Even when you are looking straight ahead, you can see a yellow object that is not in front of you “in the corners of your eyes” much sooner than any other color – even red. Scientists describe this as follows: “Lateral peripheral vision for detecting yellows is 1.24 times greater than for red.”

Many experts also point out that colors such as yellow or greenish-yellow are more visible to the human eye under dimmer conditions compared to red.

Yellow was also chosen as the colour of “positive thinking”, and identifying benefits, by De Bono in his Six hat theory.

It stands to reason that yellow is a good colour to stimulate the brain into rapid thinking and to encourage generating quick and rapid thinking, brainstorming and discussions around a subject area.  Using yellow  -especially bright yellow or yellow-orange mixtures like the colour of school buses in America –  in an environment, will allow for stimulating discussions, but will also bring the noise level up and may be a distraction when used for large areas in a classroom or learning environment.  Babies cry more in yellow rooms, and people loose their tempers easier in all yellow rooms.  As it attracts the eye, it is used for large farm equipment, as a warning light on traffic lights and as an indicator on cars, and for the well known “yellow sticky notes”.

It has been found that light yellow (happiness, warmth, summer energetic, lively) together with green (nature, trees, comfort) are the preferred colours for large areas when students reach high school age, whereas pure primary colours like bright red,  bright blue and pure, sunny yellow are the preferred colours for large areas in kindergarten and early primary years.

Blue

 The color of the sky and the ocean, blue is one of the most popular colors. Blue has a ’split personality’, and in our language, ‘having the blues’ or ‘being blue’ depict being sad, while the French uses blue to depict surprise (’sacre bleu!’)  Lighter shades of blue are seen as peaceful and tranquil, and causes the body to produce  chemicals that promote feelings calmness.  For this reason it is often seen in bedrooms.  Darker shades of  blue are usually associated with dignity and loyalty, and even high class – an old phrase for the upper class of society was “blue stocking”. 

When used alone with no warm accents, blue can also be cold and depressing. Fashion consultants recommend wearing tints and hues of darker blue to job interviews because it symbolizes dependability and loyalty. People are more productive in blue rooms when required to do individual work, or thinking deeply. Studies show weightlifters are able to handle heavier weights in blue gyms.  It is no wonder that De Bono chose blue as the hat for promoting and focusing on problemsolving, to look for new ideas/leadership, and thinking about thinking (metacognition).

In September 1981, Dr. Wolfarth of Edmonton, Canada, studied the impact of light and colour on off task behaviour, in six year old students.  He found that by only replacing the cool white fluorescent light fixtures and the semi-gloss white walls with full spectrum Duro-test Vita-Lite light fixtures, and painting the walls light blue, the off task behaviours decreased by 22%.  It should be noted that the students spent the major part of their day in this classroom environment.  In subsequent studies, where students spent their time in and out of this type of environment all day, the results were also erratic.  (The normal ‘visual noise’ on the walls, e.g. the notes and posters on the orange and red bulletin boards, were retained.  The same students and the same teachers participated throughout the trial.  The classroom routine was not changed at all.  Thus all other factors stayed the same.)  This is a significant decrease in off task behaviour.  Once again, colour and light seem to play an important role in how students learn, and how long they can stay on task, with light blue and natural light seeming to promote concentration and on task behaviour, while also lowering blood pressure.   

Red

Red stimulates a faster heartbeat and breathing, and is seen as an emotionally intense colour. It is also the color of love. Red clothing gets noticed and makes the wearer appear heavier. Since it is an extreme color, red clothing might not help people in negotiations or confrontations. Red cars are seen as symbols for driven, fast responses and speed, and are popular targets for thieves. In decorating, red is usually used as an accent, as it becomes very overpowering when used alone or for covering all the walls in a room. Decorators say that red furniture should be perfect since it will attract attention.

The red hat was chosen by De Bono to illustrate our emotions about a topic.  Using the red hat, we can convey our instinctive gut reaction or statements of emotional feeling (without having to worry about any justification).

Red in classrooms are usually used as accents like on bulletin boards.  It will draw the student’s attention, but not as much as yellow.  It brings warmth and balance to cooler rooms where blue or green may be the main colours on the walls.  It should be used very sparingly in rooms where autistic students are taught.

Green

Green is a colour found abundantly in nature, and signifies growth, rebirth, and fertility. In Muslim countries, it is a holy color and in Ireland, a lucky color. It was the color of the heavens in the Ming Dynasty, and so green jade became a valuable commodity. Today’s greens provoke strong reactions. People usually either love it or hate it. It is also interesting that different hues or shades of green can elicit different reactions from people.  Pea soup, green jelly, sleazy motel carpet, dreary hospital walls, ecology, emeralds, wasabi, and sage. Would you rather be green with envy, green behind the ears, or green around the gills? (Idiomatic American English for extremely envious, immature or nauseated.) 

It is the easiest color on the eye and can improve focus on other areas of importantce, e.g. red or yellow bulletin boards. In Zimbabwe, all military vehicles are painted in a mixture of different hues of green, to make it less visible.  Due to many accidents occuring with these vehicles in broad daylight, it is now law that all military vehicles will drive with their lights on when driving on main roads.

It is a calming, refreshing color. People waiting to appear on TV sit in “green rooms” to relax. Hospitals often use green because it relaxes patients. Brides in the Middle Ages wore green to symbolize fertility. Dark green is masculine, conservative, and implies wealth. The ‘greenback’ refers to money.  In Feng Shui, green eases absent-mindedness, nervousness and rudeness.  It also represents quietude, persistence, patience and hard work.

Green does not attract the eye or stimulate the brain like red or yellow.  De Bono chose green as the colour to associate with deeper investigation, and for seeing where a thought goes. 

Green has been used successfully in rooms where students with autism are being taught, especially if the floor and the walls are duller hues of green.

 White

In Western societies, brides wear white to symbolize innocence and purity. White reflects light, and is important in classrooms to make small spaces seem bigger. White is popular in decorating and in fashion because it is light, neutral, and goes with everything. However, white shows dirt and is therefore more difficult to keep clean than other colours, and thus impractical in classrooms as it will show scuff marks. Doctors and nurses wear white to imply sterility.

As mentioned in the section under the colour ‘blue’, full spectrum white light is really important to lower blood pressure and stope some behaviour management issues in classrooms.  Light appears colorless or white. Sunlight is white light that is composed of all the colors of the spectrum.  A rainbow is proof. You can’t see the colors of sunlight except when atmospheric conditions bend the light rays and create a rainbow. You can also use a prism to demonstrate this. 

There are 1,000 plus terms used to define whites, off-whites, and beige. Adjectives such as glistening, pearly, shimmery, blinding, glittering, and gleaming were frequently coupled with white. More common terms, such as ivory, ecru, parchment, vanilla and cream, were used for off-whites and very light browns.  For classrooms, it is important to remember that there are many different kinds of ‘white’.  It ranges from cold white with blue and purple undertones to pinkish and yellow which are warmer, and perceived to be ‘friendlier’.  Depending on the effect you want to achieve, decide carefully whether you want to use white on large wall areas, as it can be harsh on the eyes and show marks, but will not compete with accent areas like bulletin boards. When used on ceilings, the rooms will seem bigger and the less confining.
