Adding colour to resins

[Lez0]

Hi all
I want to print a part in black, but really dark black. The part is a light baffle so it has to stop the light.
I can't find a truly black resin, they all seem to be a bit translucent.
One option is to add a black tint to the resin, you can buy them in different colours.
Has anybody tried this?

Well I've added black to the smoky black and have done a few prints.
One thing is obvious, you have to mix the dye in really well. I put it in a bottle and shook vigorously it for a few minutes just before use.
The prints turned out really black.
