HEAROSUltimate Softness Series Foam Earplugs, 40-Pair

Are they suitable for children? Or would they be too big for kids' ears?

Why does this listing show green colored and curvy shaped ear plugs? The Hearos I use and want to reorder are flesh colored.

Are these flesh colored or light purple? The picture makes them look light purple here, but I was hoping for a neutral skin tone color.
