The world around us is colourless. The light from the sun shines on us in transparent waves of energy. Light is colourless until it enters the human eye which has evolved to translate energy waves into colours. Short waves translate to reds, oranges and yellows. Medium waves translate to greens and long waves translate to blues, indigo and violets.
The theory behind this is evolution. For example humans relied on knowing what was safe or ready to eat for survival. Lower energy colours (reds, oranges and yellows) can be considered warm and attract attention. Higher energy (blues, indigo, violet) can be considered cool and cerebral. Medium waves (greens) balance.
Black is an absence of colour, white is all the colours mixed together and grey is neutral.
In my work I explore our emotional response to colour and harmony.
