Colour vision deficiency
Colour Blindness
Vision is the most important human sensor: 90% of all information received is via vision, 5% via hearing, 2% touching, 2% tasting, 1% smelling. The loss of information due to inadequate colour decoding prevents or slows down comprehension, increases reaction time and generally lowers the quality of life.

8% of men and 0,5% of women have colour deficiency or colour blindness in the civilized word. According to the previous statistic there are 32,6 million CVD men in USA, Japan and West-Europe.

Colour Blindness
Colour deficient children encounter problems at kindergarten, at school by painting red grass, green roofs, not being able to solve math problems etc. And can be the subjects of accompanying ridicule and jokes when not able to see their colourful books or maps or the board properly.
Colour blindness and colour deficiency
 
Colour Blindness
The human eye can simultaneously detect three primary colours, red green and blue. All other colours are obtained by through the mixing of the three primary colorus. In the case of color deficiency one or more primary colours are not detected in the normal way, while people who are colour blind see shades of grey only (total colour blindness).

Under the most recent theory of colour vision, color blindness is recognized as an extreme case of color deficiency.
