How to enter custom RGB values on Surface colors??

[Anonymous]

I'm a little rusty from not using Archicad in a few years but there used to be an easy way to enter custom RGB values in the surface settings but I cant seem to find how to do it anywhere.

I'm sure its right under my nose but can someone point me in the right direction?

thx!

(FYI-I have the RGB values from Sherwin Williams and want to match them for doing colors on exterior materials--I realize its not an exact match but its good enough for my purposes)
