How to paint my walls as the sample (image) in different colors and why my walls near the grounds are colored.
What settings to change in my Render Menu or what settings to set on material settings.[img]
Regarding why the walls near the ground are colored, I suspect that is from global illumination (the rendering calculating light bouncing off the green grass). Thus the change in wall tint at the elevation facing the lawn. It appears there is also some ambient occlusion creating a slight shading right where the walls meet the ground. Both should be controllable, but I haven't worked enough with CR to guide you on that point.
