RAINBOW DUST - PRO POWDER
Powder Colorant - Deep Purple
Matte, concentrated deep purple powdered food coloring
Rainbow Dust Deep Purple Pro Powder is a concentrated powdered food coloring formulated to remain a stable deep purple without shifting toward indigo blue or magenta red after drying. It is specially suited to moisture-sensitive surfaces: cocoa butter, tempered chocolate, meringue, buttercream, and royal icing. Use it dry with a brush for shaded effects, or dilute it in a neutral food-grade alcohol for precise edible painting.

Uses
- Coloring cocoa butter for spraying on entremets to create a deep purple velvet effect.
- Tempered white chocolate colored throughout for molded chocolates or purple decorative panels.
- Purple buttercreams and royal icings, with no added moisture, for impeccable piping stability.
- Shaded effects on sugar-paste flowers: peonies, lilacs, lavenders, and orchids with gradients from light to dark.
Note: dilute only with a neutral food-grade alcohol, never with water, which would make the surface soggy. Add gradually: the pigment is highly concentrated, so it is better to build up the intensity than to correct an excess.

Frequently asked questions
Why choose a powder rather than a gel for purple?
The powder is compatible with tempered chocolate and cocoa butter, which liquid or gel coloring would cause to seize. It also keeps longer without drying out.
Could the purple shift toward blue or pink over time?
No, the formula precisely balances the E122 and E133 colorings to remain a stable deep purple after drying and crystallization.
Can it be used for Halloween decorations?
Yes, its intense deep purple is a common shade for Halloween decorations, either on its own or paired with a green such as Racing Green or Forest Green.
