We know from the book that Zira gets manicures regularly, bless his pampered heart, and it seems like we've all collectively agreed that Crowley paints his nails black. Now that they don't have to be so cautious about who sees them out and about, they go out and get manicures together because they're precious.
GOOD. That’s exactly how it should be. Now, I’m FAIRLY certain we never see or read about Aziraphale having painted nails, just well-manicured ones, so PLEASE imagine the first time Crowley coaxes him into having them painted in some kind of soft color- shimmery pale pink or pale blue or (perhaps there’s a little magic involved, but the human sort) tartan to match his bowtie.
