Transparent resin needs color that enhances clarity rather than fighting it. Castin' Craft Transparent Dyes dissolve completely into casting resin, creating genuine see-through color without the cloudiness that pigments introduce. The dye molecules disperse evenly throughout your pour, maintaining optical clarity from edge to center, critical for layered pieces, embedded objects, or jewelry where light transmission matters.

Liquid concentrate means precise color control. Add drops until you reach the intensity you want, from barely-there tints to saturated jewel tones. Colors blend smoothly for custom hues; mixing blue and yellow produces actual transparent green, not murky compromise. One-ounce bottles provide enough dye for multiple projects while staying manageable for storage and handling.

These dyes work specifically with polyester and polyurethane casting resins. The formulation accounts for resin chemistry, ensuring stable color that won't separate, fade, or create curing problems. Perfect for creating colored windows in larger castings, building gradient effects through successive pours, or achieving that glass-like quality in decorative and functional resin work.
