Chestnut (color) color called "chestnut" in Crayola crayons. This colour was also produced in a special limited edition in which it was called Vermont maple syrup. At the request of educators worried that children (mistakenly) believed the name represented the skin colour of Native Americans, Crayola changed the name of their crayon colour "Indian Red", originally formulated in 1958, to "Chestnut" in 1999. In reality, the colour Indian red has nothing to do with American Indians but is an iron oxide pigment the use of which is popular in India. Chestnut (color) Chestnut is a colour, a medium reddish shade of brown
Color anomaly Color anomaly Colour anomaly, sometimes referred to as partial colour blindness, is an inherited condition in which people have full trichromatic colour vision, but do not make the same colour matches as the majority of the human population. It is much more common than dichromacy or other forms of colour blindness, affecting about 6% of human males in Northern European populations. Two forms are common, known as protanomaly and deuteranomaly. In order to match a given spectral yellow light, protanomalous observers need more red light in a red/green mixture than the majority of observers, and deuteranomalous observers need more green.
