## Validation Error: Color Names

### Error: XXX is not one of the standard 16 color names

According to the CSS specifications, only the basic 16 named colors can be specified by name. Other colors must be specified using hex codes or numerical RGB values. All browsers that currently support CSS also recognize the expanded 140 named colors, but there is no guarantee that this will always be true.
