Connecticut artist Michael Rothman got his hands on some Kremer YInMn blue pigment in 2019 and produced his own paint, “hand milling the dry material in acrylic emulsion resin,” he said.

Acrylic paint tends to have the edge in vibrancy and it's also UV-resistant, allowing it to retain the original color for a longer period of time, rather than fading under direct sunlight.

Semple’s Black 3.0 paint—the blackest, flattest acrylic paint available on the planet—absorbs 99% of all the visible spectrum. Yolo does the opposite.
