At least that's the case in my studio now. I finally got the guts to paint over the green walls and I have to say that it makes a huge difference. I love it! The new color is not a stark white, but a softer, warmer off-white. It's called Pointing from Farrow & Ball... although I did get it color matched to a different brand.
I did some rearranging and put up some shelves, too. The shelf brackets came from Ikea and I spent about $12 on a piece of 1x12 pine board from Home Depot. I had them cut it into four 3' strips, so now I have 4 shelves to store all my printmaking supplies. Yay!
