AHi, I have been reading on how to make glow in the dark icing. Most of the sites I have looked at talks about using green jello or orange jello, and talks about neon colors. Ok my question is can you use a different color of jello or do you have to use the 2 colors green and orange. If you can use different colors do you need to color the icing the same color as the jello. Thank you for your help.

I don't think I have ever heard of a true glow in the dark icing - I have heard that tonic water (contains Quinine) will glow under a black light.  Adding that to your frosting should make the icing fluoresce under a black light.

I found an article that talks about the tonic water and why the jello is needed for colored icings

Hopefully someone else will happen along that has more experience or details to share.  Good Luck!

AYeah, it's not going to literally glow when the lights go out, just look a little cool under black light.
