Powdered Colorant - Deep Purple

• Stabilized deep violet: the Deep Purple shade is formulated to remain a true deep violet after application and drying, without shifting towards red-magenta or blue-indigo. This is one of the major challenges of low-end violet dyes that often shift to blue after crystallization.
• Compatible with chocolate and cocoa butter: the powder form does not add any water molecules that would cause tempered chocolate to grain or set prematurely. This is the decisive advantage over liquid dyes, which are incompatible with chocolate. For coloring cocoa butter intended for spraying on entremets, Deep Purple is the pro reference option.
• Performance on meringues and royal icing: the powder incorporates without loosening Italian meringue or softening royal icing. You maintain a firm consistency and impeccable hold, where a liquid dye would soften the preparation.
• Highly concentrated pigmentation: 5 g of Deep Purple powder represent the equivalent intensity of several bottles of liquid dye. The consumption per gram is therefore particularly economical for regular professional use.
• Dual application method: direct brush application for shaded and gradient effects, or dilution in food-grade alcohol (Rejuvenator Spirit, vodka, kirsch) for edible painting with sharp lines. One product, two decoration techniques.
• Long shelf life: the powder form keeps for several years in its resealed pot protected from moisture, unlike liquid colorings which can oxidize, partially dry out, or lose intensity over time.
• Rainbow Dust Reference: British brand recognized since 1995 in the professional Cake Design sector. Quality guarantee and product consistency for repeated shop productions.

1. Surface preparation: ensure the surface is completely dry and stable. On sugar paste, wait 10 to 15 minutes after spreading for the surface to harden slightly. On tempered chocolate, wait for full crystallization (minimum 30 minutes).
2. Brush preparation: use a fine, soft-bristled food-safe brush, completely dry. Any moisture will cause pigment clumps that mark the surface unevenly.
3. Picking up pigment: tap the brush tip into the pot to take a small amount of powder. Then tap the brush above the pot to remove excess.
4. Progressive application: apply with light tapping or circular motions on the surface. The color intensifies gradually with each pass, allowing you to precisely control the final effect.
5. Shaded and gradient effects: for a gradient, start from a central point with more pigment, then blend outward by reducing pressure. Ideal for reproducing deep violet effects, floral shading, or chromatic transitions.
6. Fixation: the powder naturally adheres to moist or very smooth surfaces. On already dry sugar paste, you can fix it by lightly brushing with vodka to anchor the pigment permanently.
7. Final precaution: before handling, gently blow or tap the piece on clean parchment paper to remove unfixed particles and avoid transferring pigment to other pieces in production.

1. Choice of food-grade alcohol: use Rejuvenator Spirit Rainbow Dust specifically designed for diluting food powders, or if unavailable, neutral vodka, sugar-free kirsch, or grain alcohol at a minimum of 40°. The alcohol evaporates quickly and does not add extra sugar to the base.
2. Mix preparation: pour a small tip of Deep Purple powder into a ceramic dish or glass container. For individual production, the equivalent of a knife tip is more than enough.
3. Progressive dilution: add 3 to 5 drops of food-grade alcohol with a pipette or dropper. Mix with a toothpick or brush until you get a creamy consistency, similar to slightly thick India ink.
4. Flow test: the paint should flow easily from the brush without forming thick drops. If too thick, add 1 drop of alcohol. If too liquid, add a bit of powder.
5. Application with a fine brush: use a fine brush for details or a flat brush for surfaces. The paint dries in 2 to 5 minutes depending on the amount of alcohol evaporated. You can rework areas as long as the alcohol has not evaporated.
6. Layering: for an extremely intense purple or maximum opacity, apply 2 successive layers, waiting for complete drying between each application.
7. Mix storage: prepare only the amount needed for the day's production. The alcohol evaporates and the mixture thickens within a few hours in open air.

1. Cocoa Butter Coloring for Entremets Spraying

Key application of Deep Purple: coloring cocoa butter intended for spraying with a gun on entremets. The deep velvet purple finish is one of the most sought-after finishes on plated desserts in gourmet restaurants and high-end pastry shops. The powder incorporates without causing graininess in tempered cocoa butter.

2. Tempered Chocolate Decoration and Candies

Coloring tempered white chocolate to create molded purple candies, purple decorative plaques, or macaron shells styled like chocolate. The powder mixes directly into melted chocolate without risk of graininess. A sophisticated effect for end-of-year chocolate boxes and premium events.

3. Violet Buttercreams and Butter-Based Creams

Direct incorporation into buttercreams (Italian, Swiss, French, American) to obtain a uniform deep purple. The powder adds no moisture, the consistency remains perfectly airy and smooth. Ideal for piping on cupcakes, layer cakes, and event pastries.

4. Tinted royal icings for decorated cookies

Incorporation into royal icing to achieve a uniform purple without softening the consistency. Ideal for decorated cookies with piping bags, purple Halloween shortbreads, Mardi Gras event cookies, or cardinal purple. The firm consistency of the icing is preserved.

5. Colored meringues and dacquoise

Incorporation into meringue before baking to obtain stable purple meringues. The pigment withstands low-temperature baking (90-100°C) without color shift. Particularly spectacular for Halloween, gothic, or purple-themed cake decorations.

6. Shaded effects on sugar paste flowers

Dry application with tapping to create realistic shaded effects on modeled flowers: petals of purple peonies, lilacs, lavenders, irises, orchids. Deep Purple allows gradients from light to dark by layering strokes, for a hyper-realistic effect comparable to natural flowers.

7. Themed decorations for Halloween, Mardi Gras, and events

For Halloween-themed orders (witches, gothic parties), Mardi Gras (purple/green/gold palette), royal or cardinal events, the deep purple Deep Purple stands out as the chromatic reference without compromise on intensity.

• Brush dedicated to the color: keep a brush specifically for Deep Purple. The pigment is very opaque and would color any other light color used afterward with the same brush. Mark the handle of your brush with a touch of purple pigment to avoid confusion in the lab.
• Shade test on a sample: before large-scale production, test the result on a small piece of your exact base. Depending on the composition of fondant, chocolate, or buttercream, absorption may slightly alter the final intensity.
• Food-grade alcohol at a minimum of 40°: for dilution, never use water (which soaks the base and melts the sugar) or sweetened alcohols like liqueurs (which add extra sugar). Neutral vodka, sugar-free kirsch, grain alcohol, or Rejuvenator Spirit are the recommended options.
• Progressive coloring: to incorporate into a buttercream or royal icing, start with a small amount of powder, mix, then adjust. It is safer to intensify than to correct an excess. The Deep Purple pigment is very concentrated, the intensity rises quickly.
• Precaution for aprons and work surfaces: the powder is highly pigmented and stains fabrics, light work surfaces, and tile grout permanently. Prepare a dedicated area with parchment paper under the mixing bowl.
• Store protected from moisture: keep the jar tightly closed, at room temperature (15-25°C), away from direct light and moisture. Use a perfectly dry spoon to take powder, never a wet one.
• Close the jar immediately: do not leave the jar open during decoration; particles fly away at the slightest draft and material loss is rapid.
• Combination with other pigments: Deep Purple can be combined with Black Magic to obtain very dark aubergine purples, or with a pink to create magenta shades. Test ratios on a sample before production.

Why choose Deep Purple powder rather than gel?

The powder offers 3 major advantages over the gel: full compatibility with tempered chocolate and cocoa butter (the gel would grain the chocolate), long shelf life without risk of drying out, and dry application for shaded effects impossible to achieve with a gel. However, the gel remains preferable for coloring very fatty preparations like some buttercreams where powder incorporation takes more time.

What is the difference between Deep Purple and Black Magic?

Deep Purple is a very dark purple that can appear black in small amounts but reveals purple highlights under direct light. Black Magic is a true black with a deep finish and no colored reflections. For theatrical effects, deep violet shades, or mystical themes, choose Deep Purple. For an absolute black with no reflections, choose Black Magic.

How much production with a 5 g jar?

For dry use to create shaded effects or light dusting, one jar covers about 80 to 120 individual pieces. For diluted paint use, expect 200 to 300 pieces depending on the fineness of the patterns. For incorporation into buttercream, one jar colors about 1 kg of cream to an intense purple. For tempered chocolate, one jar colors 800 g to 1 kg of white chocolate.

Does the purple turn blue or pink?

No, the Deep Purple pigment is formulated to remain a true deep purple after drying and crystallization. This is one of the major problems with low-quality purple colorants that turn blue-indigo (excess blue) or magenta (excess red). The Rainbow Dust formulation precisely balances the two pigments E122 and E133.

Compatible with tempered white chocolate?

Yes, perfectly, it is even one of the flagship applications of Deep Purple. The powder is incorporated directly into melted white chocolate without graininess or causing the chocolate to seize. For a uniform purple, mix 2 to 3 minutes with a spatula until particles are fully dispersed. The color remains stable during tempering and after crystallization.

How to avoid pigment clumps during dilution?

Pour the alcohol gradually (drop by drop at first), mix thoroughly with a toothpick, and crush any lumps against the side of the dish. The ideal consistency is creamy like slightly thick India ink. Too rapid dilution always creates lumps that would mark the surface unevenly.

Can it be used for coloring macarons?

Yes, incorporate into Italian or French meringue before macaronage, starting with a very small amount then adjusting gradually. Be careful not to add too much to avoid loosening the meringue. For surface decoration of baked shells, apply with a fine brush using diluted paint ideal for precise patterns.

Does the pigment withstand baking?

Yes, for low-temperature baking (meringues 90-100°C), maintaining excellent chromatic stability. For high-temperature baking (biscuits baked at 180°C), the color may slightly fade or shift chromatically. Recommendation: for decorated biscuits, incorporate Deep Purple into the royal icing after baking rather than into the biscuit dough itself.

Is it suitable for vegan and vegetarian diets?

Yes, the composition based on synthetic colorants E122 and E133 is compatible with vegan and vegetarian diets. No animal-derived ingredients are used in the formula. However, note the mandatory warning on E122 (Azorubine) regarding its possible effect on children's activity and attention, to be mentioned in-store for orders intended for young consumers.

Is it suitable for CAP Pastry candidates?

Absolutely, the pot format and long shelf life are perfectly suited to the CAP kit. The powder is accepted by examination juries. Particularly useful for tests requiring chromatic work on entremets, royal icing, or optional cake design decoration.
