Why pigment ratio matters with resin dyes

The ratio of dye to resin is critical. Not only does it influence the depth and vibrancy of your colours, but it can also impact the performance of the resin itself. Using the correct amount ensures your piece is both beautiful and structurally sound, while excessive pigment can inhibit full curing or cause unwanted cloudiness. ResinPro’s specialist products make precise colouring simple, whether you want transparent, marbled, or solid effects.

Quick comparison – recommended dye amounts across the range

• “Colourfun” – Liquid Epoxy Resin Colourant 25-100ml – High coverage: Economical usage—just one 25ml bottle can colour 2–3kg of resin, thanks to its highly concentrated formula. Only a few drops are needed for dramatic effect, and you can blend from vivid opacity to stained-glass transparency. See Colourfun details.
• “Renaissance” – Set of Dyes, 4 Colour Palettes: Crafted for a realistic marble effect, this set recommends a ratio from 1% (translucent) to 5% (opaque) of pigment to the total resin mass. Exceeding 5% is not advised as it may affect polymerisation. Explore Renaissance Set.
• “Colourfun Set” – Liquid Epoxy Resin Colourant Set for Solid Colour Effects: These paste pigments are highly concentrated, so a few drops tint litres of resin—perfect for transparent or opaque finishes without thinning. See the Colourfun Set.
• “Marine Palette” – Set of Dyes for Ocean Art, Epoxy Resin, and Beach Effects: Each kit features highly pigmented, odourless dyes. Using only a few drops ensures deep marine brilliance while keeping your resin safe and vibrant. Discover the Marine Palette.
• “Magic Crystal” – Transparent Resin Colour 45ml: Ideal for crystal-clear, glass-like effects. These dyes remain fully transparent with a bright finish, and a few drops are all that’s needed for precious stone-inspired results. See Magic Crystal.
• “Magic Crystal” – Set of 5 Transparent Colourants, 5 x 45ml: Perfect for custom-mixing transparent resin shades. Add dye judiciously—these deliver reliable colour effects without compromising clarity. View the Magic Crystal Set.

Remember: never exceed 5% dye by total resin mass unless suggested in product guidelines. Excessive dye risks incomplete curing or dull finishes.

Choosing your dye – which product matches your project?

Your choice of pigment depends on the artistic effect you wish to achieve, as well as the compatibility with your preferred resin:

• For vivid solid colours or stained-glass effects, Colourfun – Liquid Epoxy Resin Colourant is the top pick, suitable for both opaque and translucent finishes in all ResinPro epoxy products.
• To create natural marble effects and unique textures, the Renaissance Set delivers balanced, controlled colour—ideal for artboards, decorative panels, or layered pieces.
• When transparent tints and large castings are your aim, Colourfun Set pastes provide even distribution for effects like sea water gradients and river tables.
• For marine-inspired waves and ocean art, the Marine Palette offers perfectly matched blue tones, especially when combined with Wave-Pro powder.
• Achieving crystal-clear transparency in jewellery, geode or mineral resin projects calls for the Magic Crystal – Transparent Resin Colour, or experiment with a broader range with the Magic Crystal Set.

Each product is uniquely formulated to ensure ease of mixing, even colour saturation, and long-lasting effects, supporting beginners and professional makers alike.

How to mix resin dyes for perfect results

For best outcomes, start with a small amount—just one or two drops per 100g of resin—and add gradually, stirring thoroughly until the colour is distributed. Check the shade visually; for opaque results, you can increase toward the 5% pigment-to-resin limit. For transparent or water-like appearances, stay around the 1% mark. Always blend thoroughly to avoid uneven effects.

Mixing pigments is an exciting way to customise hues. For instance, grey tones in your resin can be made by mixing black and white liquid Colourfun dyes or blending with metallic powders, such as Sahara grey. Experiment with Colourfun to achieve the precise style you envision.

Safety, ethical, and technical points to remember

Many ResinPro dyes—including the Colourfun range and Colourfun Set—are cruelty free and vegan friendly. Most contain highly-concentrated pigments, so long-lasting coverage is guaranteed without overuse, minimising waste and risk.
