Colour
Colour is all around us. We see it all the time. Most of us have no idea the impact colour has on our lives. This impact of the many colours in our environment is usually not conscious. Sometimes we get an uneasy feeling in certain rooms or very relaxed in another, but we call this a mood. The "colour of mood" can be what is surrounding us.
Colour is a vibration of light. In dim light, the colour we see will seem different than in bright sun light. Everyone doesn't see the colour frequency in exactly the same way. For example, I see a colour I call blue-green, which to me is blue with a touch of green. Someone else may call the colour green-blue, because he sees more green than I do. Even colour-blind people are affected by colour.
Colour Classification
This colour classification of Newton is relevant even today. The colour spectrum he had arrived at is akin to the colour spectrum of a rainbow. The light is radiant but a visible energy of electromagnetic wave motion, which moves through space at an incredible speed of 186,000 miles per second. Like X-rays, or, radio signals it is transmitted through electric vibrations and magnetic fields, though, of course, at different frequencies. It moves in waves and the measure for lights wavelength is Angstrom Units(AU).
Primary Colours: Red, Blue and Yellow are considered the primary colours because they are pure colours, which are beyond production by mixing other colours. Since we can arrive at any colour by mixing these three colours in different proportions, these are rightly identified as primary colours.
Secondary Colours: If we mix two primary colours in equal parts, we get the secondary colours viz., violet, green and orange.
(violet = blue + red, green = blue + yellow, orange = yellow + red).
Characteristics of colour
Colour theorists have defined three characteristics of colours (3 dimensions of colour)
1. Hue-name of the colour.
2. Value-lightness or darkness of colour.
3.
