Colour list in Codex

Is there one? I swear there was one – but I searched by clicking randomly, then in logical order, finally I tried the search box and couldn’t find it. If it is there, could someone tell me where it is, and if it isn’t could someone add a list?

There’s one particular one I’m after that allows you to enter two hex values and then it gives you the range that you define by choice.

There was also another that Moose posted, and perhaps it’s a limitation of BBPress but I couldn’t find that on this site here, even thugh I know it’s around here…somewhere…

Thanks in advance
