Good to see something new from Stuart Semple — the guy who made the “blackest black” (Black 2.0), which everyone except Anish Kapoor can purchase…

I mean, he's released Black 3.0 and about 20 other things since then. The man is a non-stop craft supplies firehose.
I dabble a bit, and Black 2.0 (havent' tried 3.0) is like magic.
I also heartily recommend Semple's glow-in-the-dark pigment, but be sure to mix well, it's a non-soluble powder and can yield unintended 3D effects if the mix is off (or you did not mortar/pestle)
