Jade Groove is a very pale green, it almost looks silver with a hint of green. I was so disappointed with this because I wanted it to be a true green but the color is so pale you can hardly tell that it's green. (But they totally make up for this with Emerald Divine!)
Mermaid Spell is pale blue.
Ocean Rush is a bright blue, this color is stunning!
