Texture over color is my rule of thumb for creating the most inviting spaces. When people say they want "COLOR COLOR COLOR," I have to read between the lines a bit. Inherently textured pieces have a range and depth of color that is just not achievable with prints and solids.
I do think my new office may need some feathers. Masculine feathers, of course. Also, a magnified photo of a tortoise shell is destined to be my next piece of framed art.
