Apparently, black. I tried to use Wilton's candy colors, blue and red, to make purple with the white candy melts. Tried all different ratios of colors...nope, it just turned black. Once again...foiled...by Wilton....
Americolor...here I come! I will say though, I used it to make black bat cake pops with purple sugar wings. They came out great, just not purple.
So glad you could still use the "purple"! Go figure!
