That remaining halo around the twilight icons has been driving me crazy! (Yes, I've probably been staring at them more than is healthy... but those DC writers deserve only the best!) The culture icons look fine, though; maybe they used a darker matting...
Anyway, no need to hold back replacing them on my account at least. I don't quite remember what CC's was like, but we could always adjust the contrast and font if needed while keeping the base.
