Hi

A systematic color naming scheme, where hue, saturation, and lightness 
each have short lists whose keywords can be combined, offers many 
advantages:

A reasonable number of evenly distributed hues increases the chance that 
the designer finds the right one.

Adjective saturation and lightness keywords as optional modifying 
prefixes offer a systematic way of finding the right color without 
memorizing or consulting huge tables.

The combinatory nature of the system drastically decreases the number of 
keywords, and the size of lookup tables; this is good for designers and 
implementers.
No table is required to list all values. They can be calculated by the 
implementation, since the system is consistent; a dark red has the same 
lightness as a dark green, and a grayish yellow has the same saturation 
as a grayish orange.

The resulting sentences, based on a simple system, are more expressive 
than long keywords which are based on history, folklore, and flowers. 
This increase in semantic value and clarity aids accessibility, and 
maintainability, and makes it easier to use for the designer.

AFAICS, something like the color naming scheme described in
http://lists.w3.org/Archives/Public/www-style/1996Feb/0006.html
looks very promising (although I think there should be some more hues).

Tobi
