The French word for "color (US) /colour (UK)" is very similar: "couleur". What about the names of the colors in French? Here is the list:

Examples

• Lance Armstrong porte le maillot jaune.
  Lance Armstrong wears the yellow jersey (=he is the leader in the Tour de France).
• De quelle couleur est-il ? Il est rouge.
  What color is it? It is red.
• Elisabeth et Sylvie ont les yeux bleus.

• Allez les bleus !
  (encouraging the team in blue) Come on!

Hair

NB: "cheveux" means "hair". Unlike the English, it is plural.

Example

• Il a les cheveux blonds.
  He has fair hair.
