Mike, I would do the lighter color to the bottom of the windows, but since you can't measure height in a picture that may be to high. Another thought is maybe painting just 1 wall to break up the white.
Your shop is awesome as is but my vote is is 0204 all the way up. Personally, that much white would kill me. I had an all white kitchen in my old house and I felt like I was in a doctors office all the time. I swore I would never do that again in any room.
