Unfortunately, I don't have Silver Glow, but I do the other two. These matches are for Shimmerlocks.
Srarsong's pink is Posey and the light purple is Blossom. I'm not sure about the darker pink. I thought it was Heartthrob but I don't have any of that hair, but it would be my best guess (not guaranteed though)
Thistle Whistle's yellow is Merriweather. I don't know about the neon pink and I'm not confident enough to guess.
