Concentrated fluorescent pigments transform into vibrant tempera paint with simple water mixing, giving you control over opacity and consistency for everything from bold poster work to translucent layering. These Jack Richeson powders deliver intense color in normal lighting, then activate dramatically under black light, ideal for theatrical sets, event signage, or experimental mixed media. The dry powder format means extended shelf life and zero waste from dried-out liquid paint.

Mix equal parts powder and water for standard coverage, or adjust ratios to suit your application: more water for transparent washes, less for opaque coverage that stands up to viewing distance. Each half-pound jar yields substantial quantities of working paint compared to pre-mixed alternatives. Six fluorescent colors provide the core palette for black light reactive work, whether you're creating stage backdrops, educational displays, or glow-effect illustrations. The powder stays viable indefinitely when stored dry, so you mix only what each project requires.
