I'm finding I'm not as happy with the way the larger blocks of dark coral stand out, so I'm going to pull some of them -- it really works better in the narrower strips. But I like the darker yellow ones, so I'm definitely adding more of those.
I'm still trying to get the balance right, taking my glasses off and looking for dark spots or too much blue (this same technique works for distributing lights on the Christmas tree evenly -- two rare times being nearsighted has its advantages), then going back to the stacks of remaining blocks to find replacements. Then repeat ad infinitum.
I think I could rearrange blocks on this for the next week and still not be satisfied.
