Paris Green-2, 4642 was originally designed in response to the artists request for a transparent green that didn't turn red. We set out to meet this challenge and developed 3 shades of this revolutionary color, Kryptonite 461 being the lightest and Paris Green-6, 4646 being the darkest. Layer over Sno White, 9995 for a neon effect. This is a great color for sculpting as well.
