First of all, I take no credit for the content on these websites I am linking. Secondly, I found these in hoping that they could be useful.

I figured these will be useful for effects makers and model skinners. RGB values would help you guys find certain colors you need. For instance, you want a Yellow-Green colored laser or something...you can check the RGB values and then go into the ord file of that weapon and input the values.

Or if you're looking for a specific color palette for a skin you're making and you need a quick reference.

Anyways, modders enjoy: http://www.tayloredmktg.com/rgb/#YE

I give full credit to this person who made the page since it was originally colors for HTML pages.

This also has some colors: http://web.forret.com/tools/color_palette.asp

I don't know how useful this would be to you guys here, but I'm using it for RGB values.

Thanks Revan, that's usefull for custom colors on instant action selection screen.
