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
Primary color of light (i.e., the spectral power distribution) reflected from illuminated surfaces coated in paint mixes, slurries of pigment particles, is not well approximated by a subtractive or additive mixing model. Color predictions that incorporate light scattering effects of pigment particles and paint layer thickness require approaches based on the Kubelka–Munk equations. Even such approaches cannot predict the color of paint mixtures precisely since small variances in particle size distribution, impurity concentrations etc. can be difficult to measure but impart perceptible effects on the way light is reflected from the paint. Artists typically rely on mixing experience and "recipes" to mix
