Duochrome is one pigment that bounces between two colors. Formulated to meet and exceed the highest industry standards, every batch is analyzed for its performance qualities – lightfastness, color value, tinting strength, clarity, vibrancy, undertone, particle size, density and viscosity. Capture shimmer, shine and light with these specialty colors that feature optical effects found in nature. The luminous quality of this palette is often seen with the sheen of a bird’s feathers, the color shifting of fish scales, or the sparkle of reflections in water. 15ml tube
