How does colour psychology work? Colour is light, travelling to us in waves from the sun, on the same electro-magnetic spectrum as radio and television waves, microwaves, x-rays etc. Light is the only part of the spectrum that we can see, which perhaps explains why we take it less seriously than the invisible power of the other rays.

Sir Isaac Newton demonstrated that light travels in waves, when he shone white light through a triangular prism and the different wavelengths refracted at different angles, enabling him to see the colours of the rainbow (the spectrum).

When light strikes any coloured object, the object will absorb only the wavelengths that exactly match its own atomic structure and reflect the rest - which is what we see. Turn this around and it is easy to understand how the colour of anything is a clear indication of its atomic structure or, in simple terms, what it is made of.

When light strikes the human eye, the wavelengths do so in different ways, influencing our perceptions. In the retina, they are converted into electrical impulses that pass to the hypothalamus, the part of the brain governing our hormones and our endocrine system. Although we are unaware of it, our eyes and our bodies are constantly adapting to these wavelengths of light.

Colour is energy and the fact that it has a physical effect on us has been proved time and again in experiments - most notably when blind people were asked to identify colours with their fingertips and were all able to do so easily.

Let's take a look at some examples of colour, and their psychological properties...

RED. Physical
Positive: Physical courage, strength, warmth, energy, basic survival, 'fight or flight', stimulation, masculinity, excitement.
Negative: Defiance, aggression, visual impact, strain.

Being the longest wavelength, red is a powerful colour. Although not technically the most visible, it has the property of appearing to be nearer than it is and therefore it grabs our attention first. Hence its effectiveness in traffic lights the world over. Its effect is physical; it stimulates us and raises the pulse rate, giving the impression that time is passing faster than it is. It relates to the masculine principle and can activate the "fight or flight" instinct. Red is strong, and very basic. Pure red is the simplest colour, with no subtlety. It is stimulating and lively, very friendly. At the same time, it can be perceived as demanding and aggressive.

BLUE. Intellectual.
Positive: Intelligence, communication, trust, efficiency, serenity, duty, logic, coolness, reflection, calm.
Negative: Coldness, aloofness, lack of emotion, unfriendliness.

Blue is the colour of the mind and is essentially soothing; it affects us mentally, rather than the physical reaction we have to red. Strong blues will stimulate clear thought and lighter, soft blues will calm the mind and aid concentration. Consequently it is serene and mentally calming. It is the colour of clear communication. Blue objects do not appear to be as close to us as red ones. Time and again in research, blue is the world's favourite colour. However, it can be perceived as cold, unemotional and unfriendly.

YELLOW. Emotional
Positive: Optimism, confidence, self-esteem, extraversion, emotional strength, friendliness, creativity.
Negative: Irrationality, fear, emotional fragility, depression, anxiety, suicide.

The yellow wavelength is relatively long and essentially stimulating. In this case the stimulus is emotional, therefore yellow is the strongest colour, psychologically. The right yellow will lift our spirits and our self-esteem; it is the colour of confidence and optimism. Too much of it, or the wrong tone in relation to the other tones in a colour scheme, can cause self-esteem to plummet, giving rise to fear and anxiety. Our "yellow streak" can surface.

GREEN. Balance
Positive: Harmony, balance, refreshment, universal love, rest, restoration, reassurance, environmental awareness, equilibrium, peace.
Negative: Boredom, stagnation, blandness, enervation.

Green strikes the eye in such a way as to require no adjustment whatever and is, therefore, restful. Being in the centre of the spectrum, it is the colour of balance - a more important concept than many people realise. When the world about us contains plenty of green, this indicates the presence of water, and little danger of famine, so we are reassured by green, on a primitive level. Negatively, it can indicate stagnation and, incorrectly used, will be perceived as being too bland.

VIOLET. Spiritual
Positive: Spiritual awareness, containment, vision, luxury, authenticity, truth, quality.
Negative: Introversion, decadence, suppression, inferiority.

The shortest wavelength is violet, often described as purple. It takes awareness to a higher level of thought, even into the realms of spiritual values. It is highly introvertive and encourages deep contemplation, or meditation. It has associations with royalty and usually communicates the finest possible quality. Being the last visible wavelength before the ultra-violet ray, it has associations with time and space and the cosmos. Excessive use of purple can bring about too much introspection and the wrong tone of it communicates something cheap and nasty, faster than any other colour.

ORANGE.
Positive: Physical comfort, food, warmth, security, sensuality, passion, abundance, fun.
Negative: Deprivation, frustration, frivolity, immaturity.

Since it is a combination of red and yellow, orange is stimulating and reaction to it is a combination of the physical and the emotional. It focuses our minds on issues of physical comfort - food, warmth, shelter etc. - and sensuality. It is a 'fun' colour. Negatively, it might focus on the exact opposite - deprivation. This is particularly likely when warm orange is used with black. Equally, too much orange suggests frivolity and a lack of serious intellectual values.

GREY.
Positive: Psychological neutrality.
Negative: Lack of confidence, dampness, depression, hibernation, lack of energy.

Pure grey is the only colour that has no direct psychological properties. It is, however, quite suppressive. A virtual absence of colour is depressing and when the world turns grey we are instinctively conditioned to draw in and prepare for hibernation. Unless the precise tone is right, grey has a dampening effect on other colours used with it. Heavy use of grey usually indicates a lack of confidence and fear of exposure.

BLACK.
Positive: Sophistication, glamour, security, emotional safety, efficiency, substance.
Negative: Oppression, coldness, menace, heaviness.

Black is all colours, totally absorbed. The psychological implications of that are considerable. It creates protective barriers, as it absorbs all the energy coming towards you, and it enshrouds the personality. Positively, it communicates absolute clarity, with no fine nuances. It works particularly well with white. It communicates sophistication and uncompromising excellence. It creates a perception of weight and seriousness (it is a myth that black clothes are slimming). Black is essentially an absence of light, since no wavelengths are reflected and it can, therefore be menacing; many people are afraid of the dark.

WHITE.
Positive: Hygiene, sterility, clarity, purity, cleanness, simplicity, sophistication, efficiency.
Negative: Sterility, coldness, barriers, unfriendliness, elitism.

Just as black is total absorption, so white is total reflection. In effect, it reflects the full force of the spectrum into our eyes. Thus it also creates barriers, but differently from black, and it is often a strain to look at. It communicates, "Touch me not!" White is purity and, like black, uncompromising; it is clean, hygienic, and sterile. The concept of sterility can also be negative. Visually, white gives a heightened perception of space. The negative effect of white on warm colours is to make them look and feel garish.

BROWN.
Positive: Seriousness, warmth, Nature, earthiness, reliability, support.
Negative: Lack of humour, heaviness, lack of sophistication.

Brown usually consists of red and yellow, with a large percentage of black. Consequently, it has much of the same seriousness as black, but is warmer and softer. It has elements of the red and yellow properties. Brown has associations with the earth and the natural world. It is a solid, reliable colour and most people find it quietly supportive - more positively than the ever-popular black, which is suppressive, rather than supportive.

I have always been fascinated by colour, and peoples' perception of colour and the symbollic properties of colour throughout history.

I have gathered collections of my favourites - coded by the colours of the spectrum - and I hope you enjoy their vibrations, as much as I did coveting them... The Artists being paid tribute to here deserve a WIDER audience.
