Colored tints in UV resin?

Does anybody have any experience with this? I’ve heard you can use translucent tints but not opauqe. This makes sense due to the fact that the UV rays will get through the translucent but not the opaque. You never know though. I know I have to use a small batch of catalized resin to lay my black rice paper lam down, before I glass with UV. I’ve used the UV now a couple times and it works great (clear glass jobs), but I like to use colored tints and wonder what I can get away with. Any help is greatly appreciated. Thanks- ryan
