Also, there is App::ColorNamer, which uses the CSS colors only, but they too are just in an array in the sourcecode so you can easily tweak that to your needs. holli You can lead your users to water, but alas, you cannot drown them.	[reply] [d/l]

Your list looks a little bit short: `>perl -nE '@x=split;$seen{join(" ",@x[0,1,2])}++;END{say 0+keys%seen}' + < /usr/share/X11/rgb.txt 512 >wc -l /usr/share/X11/rgb.txt 782 /usr/share/X11/rgb.txt >` [download] (From Slackware64 14.2) Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply] [d/l]

That's because rgb.txt contains a <Reveal this spoiler or all in this thread> of duplicates and probably system dependent variations. I complied with the list on Wikipedia I linked to. holli You can lead your users to water, but alas, you cannot drown them.	[reply] [d/l]

Still, Slackware's rgb.txt defines 512 unique colors (and 270 dupes). The Xorg version is identical to the Slackware version. Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply]
