My Rain-Beau is great light blue for spring and summertime. I have very fair skin, and light-colored nail polishes still have a lot of pigment against my skin tone. This blue still looks light, airy, and fresh on my nails. It’s very beachy and summery color. I think “Cinderella blue” is a good description; on me, I can see a subtle purple/lavender undertone in certain lights.
