Powdered Food Colouring & Colour Dusts

Powdered Food Colouring for Baking and Decorating

Powder food colouring covers two distinct applications in baking — colouring recipes directly (batters, icings, and fondant) and decorating finished surfaces (dusting, painting, and highlighting). Our collection includes products suited to both, so it's worth understanding which type you need before selecting. For gel and liquid options, visit our gel food colouring range, or browse the full food colouring collection for all types.

Rolkem Rainbow Spectrum Colour Dusts

Rolkem Rainbow Spectrum dusts are professional-grade colour dusts (also known as petal dusts or lustre dusts) used for decorating cakes, sugar flowers, cookies, and confections. Available in over 25 shades — including Magenta, Royal Blue, Turquoise, Peacock, Lavender, Navy, Midnight, and Wedgewood Green — the Rainbow Spectrum range gives decorators precise control over surface colour and shading.

Rolkem dusts can be used in several ways:

• Dry dusting — brush directly onto fondant, sugar flowers, macarons, or biscuits for a soft, matte colour effect
• Edible paint — mix with clear alcohol (such as vodka or rejuvenator spirit) to create a smooth, brush-ready paint for detailed work on cakes and decorations
• Chocolate colouring — mix directly into melted chocolate for vibrant colour without altering the chocolate's texture
• Airbrushing — mix with an appropriate carrier for use in an airbrush machine

Titanium White Powder

Titanium white powder (titanium dioxide, food grade E171) is used to add bright, clean white to fondant, buttercream, royal icing, and other decorating mediums. It is particularly useful for lightening or brightening colours, making fondant appear cleaner and more opaque, and achieving stark white results in royal icing without the yellow tint that can come from icing sugar alone.

We stock titanium white in 100g (Sprinks and food-grade E171) and bulk 500g sizes, suitable for both home and professional use.

Black Cocoa Powder — Natural Brown and Dark Food Colouring

Black cocoa powder is a naturally derived, ultra-processed cocoa that produces deep, dark brown and near-black colour in batters, frostings, and icings. It is the key ingredient in Oreo-style biscuits and dark chocolate cake, producing a significantly deeper colour than standard cocoa. As a natural food colouring powder, it adds both colour and rich chocolate flavour without the use of synthetic dyes.

We also stock low fat and high fat cocoa powders for baking applications requiring natural brown colour. Cocoa powders are available in 500g and bulk 5kg sizes, making them cost-effective for high-volume production.

For those specifically searching for brown food colouring or a naturally-derived dark colour for cake batter or frosting, black cocoa powder is the most effective and flavourful option available.

Using Colour Dusts as Edible Paint

One of the most popular applications for Rolkem Rainbow Spectrum dusts is creating edible paint for hand-painted cake designs. To make edible paint from colour dust, mix a small amount of dust with clear alcohol — vodka, rejuvenator spirit, or lemon extract all work well. The alcohol evaporates quickly as you paint, leaving only the colour behind. This technique works on fondant-covered cakes, chocolate, sugar decorations, and macarons.

For gold and metallic paint effects, our food colouring range also includes Colour Mill Edible Gold and Silver Leaf Transfer Sheets for premium metallic finishes.

Luster Dust and Shimmer Effects

Luster dust and edible shimmer dust add a pearlescent or metallic sheen to cakes, cookies, chocolates, and even drinks. The Rolkem Rainbow Spectrum range includes several shades with natural shimmer properties, perfect for wedding cakes, celebration bakes, and premium dessert presentations. For luster dust for drinks — a growing trend in cocktail and hot chocolate presentations — a small pinch stirred into a beverage creates a sparkling shimmer effect.

FAQs About Powdered Food Colouring

What is the difference between powdered food colouring and gel food colouring?

Powdered food colouring adds no moisture to a recipe, making it ideal for dry mixes, chocolate work, and applications where extra liquid would alter the texture. Gel food colouring is water-based and more commonly used for icings, batters, and fondant. For most standard baking applications, gel is more convenient; for chocolate and dry mixes, powder is the better choice. Browse our gel food colouring collection for gel-based options.

Can you use colour dust in chocolate?

Yes — Rolkem Rainbow Spectrum dusts can be mixed directly into melted chocolate to add colour. Because the dust is moisture-free, it integrates into the chocolate without causing seizing. This makes it a useful alternative to oil based food colouring for certain chocolate applications, particularly when small amounts of colour are needed.

Is black cocoa powder the same as regular cocoa powder?

Black cocoa powder is a heavily Dutch-processed cocoa that has been alkalised to a much greater degree than standard cocoa, resulting in its distinctive near-black colour and intensely smooth chocolate flavour. It is not interchangeable with standard cocoa in all recipes — the flavour and acidity level differ — but it is an excellent natural dark food colouring for batters, frostings, and decorating applications.

What is titanium white powder used for in baking?

Titanium white powder (food grade E171) is used to add opacity and brightness to white icing, fondant, and buttercream. It prevents the yellow or grey tint that can appear in white decorating mediums, producing a clean, bright white finish. It is commonly used in wedding cake decorating, royal icing for sugar cookies, and fondant work where a stark white result is required.

Are the colour dusts suitable for dietary requirements?

Many products in our powdered colour range are suitable for specific dietary requirements. Browse our vegan food colouring, gluten free food colouring, and halal food colouring collections for verified options, or check individual product labels for certification details.

Do you stock bulk powdered food colouring?

Yes — black cocoa powder is available in a bulk 5kg size, and titanium white powder is available in 500g. For bulk gel or oil based food colouring options, see our gel food colouring and oil based food colouring collections.
