What the heck are these?

i was given a colony of about 30 heads and my friend didn't know what they were because he got them in a trade and didn't want them. They started opening last night. Under blue LEDs they have a bluish purple center, and bright green outside. I don't think it's enough to be mean green, so I'm thinking they may be candy apple green. I'm open to suggestions. The pic is from last night taken with my camera flash. You can sort of see the coloration. The blues on my light bleach out my pics if I don't use flash.
