How Do Crayons, Paint, and Markers Work?
By Sharon Fabian
  

1     Crayons, paints, and markers all have one thing in common - pigment. Pigment is another word for color. Pigments are chemicals. Each one reflects certain wavelengths, or colors, of light and absorbs certain other ones. This is what makes each pigment look a different color.
 
2     Many pigments are made from chemical compounds that include metals. Iron, titanium, and chromium are all used in pigments.
 
3     Iron is a shiny, silvery metal. It turns red, as in rust, when mixed with oxygen. It is used in colors including reds, yellows, browns, and oranges.
 
4     Titanium is a bright white chemical. It is used in fireworks and in toothpaste. It is also used to make white and bright yellow pigments.
 
5     Chromium is a shiny, gray metal, but when added to other chemicals, it produces bright, deep colors. Chromium is one of the elements in gemstones such as rubies and emeralds. It is used in yellow and green pigments.
