I have come across this great function/command. Colour to RGB, you can do this:

col2rgb("peachpuff")
//returns hex

It will return one hex value. I want to extend this using Perl, Python or PHP but I want to be able to pass in, for example, “yellow” and the function returns all types of yellows – their hex/rgb/?/etc value.

I already have a quick solution implemented, which involves mapping colour names to hex values but now I want to get more precise and use some formulas etc to determine what’s what.

However, as usual, I don’t have a clue on how to do this! So I appreciate any implementation advice on how to do this.

Thanks all

    The canonical CSS color names originated in X11 and the intersection of the sets – along with their RGB values can be – found at Wikipedia.

    A more easily parsed list can be found in various rgb.txt files scattered over the web, but these are likely the X11 set not the CSS set.

    added: Given an RGB value you can compute nearby colors by HSL conversion. Color palettes – sets of colors that go well together – are an art not a science, Google ’em.
