Possible to "colorize" Materials ?

[SomeDay]

Hello,

As an example, I'd like to change the color of the Sketchy_Shingle_Shakes to blue.
Can that be done? If so, how would I do it?

Thanks in advance.

In the materials window go to the edit tab and select the colour you want.

Wow! That was easy (because you know what you're doing).

Thank you so much!
