Amber

Amber is a shade of yellow considerably darker than bright yellow or traditional yellow.  Since it's darker, it's easier to read, making it a smarter choice for writing or drawing.
Amber is close to the color of the jewel amber, giving it its name.  It has a little bit of orange in it, helping to make the darker color.  Amber is one of the nicest colors of yellow in fancy clothing because it isn't obnoxiously bright.
