I think most lighter shades would be great, I have a light mauve/tannish color and doesn't interfere with anything.

I painted my room a light green. I love it. It is so relaxing. I don't think it affects my colors of fabric. at least I haven't notice it. I did vinyl tiles in cream and 2 light shades of green in a quilt pattern on the floor.

The more natural light you have in the room, the bolder color you can get away with. I had quite a lot of natural light in my last home, and my sewing room was a bold greenish yellow (sort of an olive color). I absolutely loved it, and noticed no affect on my color perception. My current sewing room has very little natural light and is a pale, neutral aqua.

I think anything in a pale shade ... pick the color you love and go with it!

My sewing studio is a peach color. I love it.
