quite new to this world, started learning blender with youtube 10 days ago.
So I donwloaded this material : https://www.blendswap.com/blends/view/73950
I used file>append to add it to my scene from the downloaded .blend file, with the node editor I tweaked it so that the grain appear nice on my planks :
but I can't find how to change the color, I'd like it to be darker. Apparently this is not done in the node editor.
Would anyone know where this is done? And while I'm at it, would anyone have a tutorial explaining how those materials are done? The only ones I found use an image texture, but If I understood correctly procedural material do not use textures, everything is generated.
