I think this issue was discussed earlier in the list, but it might have 
been elsewhere. Anyway, color names should _not_ be capitalized, as that 
would pointlessly deviate from common CSS practice of writing keywords in 
all lowercase and would slightly _reduce_ readability, since it is not 
common to write color names that way.

All the CSS 2 names are short, and when interpreted as English words, none 
of them are compounds. The proposed CSS 3 color names (which reflect 
existing browser practices but are hardly useful) contain many compounds, 
and for _them_ it might be argued that legibility is slightly increased by 
using uppercase at the start of each part of the compound except possibly 
the first one, e.g. LightSeaGreen or lightSeaGreen. But capitalizing the 
_first_ letter is really irrelevant here.

On the other hand, it would be disproportionate to give a warning (in 
either direction) about things like case of letters in case-insensitive 
constructs. It would reduce the credibility of other, much more important
