Pretty nice theme of letters formed by answers that rely on a certain color, and which can be clued as actual things, like "black eye," "green tea," and so forth. And on top of that, the revealers are all symmetrical. It's a simpler (I imagine) horizontal symmetry, but still, not bad at all.
My favorite part of this thing might be the ridiculous, made-up word MILLIHELEN (34A: Facetious unit defined as the amount of beauty necessary to launch one ship). I've never heard it before, and I thought that Mr. McCoy had brazenly created this word to make the grid work, but it actually has a history. Fantastic. ELEVENTY (48D: 110, to Bilbo Baggins) isn't bad, but it's not nearly as nice as "MILLIHELEN."
In addition, there are many nice bits of long-ish fill. HARMONICA (94A: Relative of a panpipe), MISNOMER (40D: "Koala bear," e.g.), ACETATE (42A: Sodium ____ (potato chip flavoring)), PROMINENT (50A: Leading), ALLEARS (73D: Rapt), and, of course, NEGLIGEE (47D: Honeymoon attire).
Best part of it all - 43D: Who said "I can't prove it, but I can say it" (COLBERT). Brilliant.
An enjoyable Sunday.
