Glow-in-the-Dark Paint that's safe for horses?

I was thinking about painting a skeleton on a horse for Halloween night turnout. Any suggestions for horsey safe glowing paint?

Im not sure about “horse” safe, but walmart had some non toxic glow in the dark paint.

I used some to make a pillowcase 3 years ago and it still glows! Though I got the kind that isnt supposed to wash out for that one.

I will look for it.

I also found a recipe for body paint using a powdered glow pigment from walmart and cold cream.
