Butter London has two really nice shades of blue: "Royal Navy" & "Big Smoke"
If those are too dark "Bluey" is pretty also. If you like dark green "British Racing Green" is gorgeous.
I'm a huge Butter London fan. After I fell in love with "All Hail the Queen" I just kept buying more.
Cafe Makeup has some good pics of it--

I love how in so many of their n/p there is great shimmer but not chuncky glitter. But if you like glitter there are some pretty ones I've bought for gifts. My daughter-in-law squealed when I gave her "Disco Biscuit" It's bright pink and sparkly, her two favorite things.
For the most part BL has great n/p but like all brands there are a few duds here and there.
Most of my n/p is Butter London & Deborah Lippmann
