This powder is a very deep blue color in temperatures under 25C / 77F. It is very light and fluffy, mixing smoothly into just about any medium. It is not UV light sensitive like some of the other pigments and will really have no noticeable change under a black light. When the powder comes in direct contact with temperatures above 25C / 77F it will turn white, or what some would call colorless.
