Get inspired by real project photos showing how various translucent and opaque colourants work within resin. Notice how effects can vary depending on thickness, layering, or blend.

Step 1: Prepare Your Resin and Workspace

Start by setting up a clean, organised workspace free from dust and moisture, as these can impact the final appearance and clarity of your resin. Wear gloves and an apron to prevent stains and protect your skin. Lay out all your colouring tools and ensure your resin system is ready for mixing. Work in a well-ventilated area, and keep your equipment scrupulously clean to avoid contamination or unwanted colour mixing.

Step 2: Select and Measure Your Colourant

Choose a colourant compatible with your resin system and desired effect. For clear, glass-like tones ideal for jewellery or geode art, opt for a transparent option such as the “Magic Crystal” – Transparent Resin Colour 45ml or the “Magic Crystal” – Set of 5 Transparent Colourants, 5 x 45ml. When aiming for deeper, more opaque finishes, a concentrated product like the “Colourfun” – Liquid Epoxy Resin Colourant 25-100ml – High coverage or the “Colourfun Set” – Liquid Epoxy Resin Colourant Set for Solid Colour Effects is best. Always start with a minimal amount—just 1–5% colourant by weight. Add more only if you want a stronger effect. Always measure your colourant carefully to avoid oversaturation, which can affect curing or the resin’s mechanical properties.

Step 3: Mix Until the Colour is Even

Pour the resin part A and part B according to your product’s instructions, then add the measured colourant. Using a mixing stick, stir slowly and thoroughly for an even result. Fast or vigorous mixing can introduce air bubbles and streaks, so take your time. Scrape the sides and bottom of your mixing vessel to ensure the colour is fully dispersed. Inspect the mixture in good light for any unblended pigment or cloudiness, especially when working with transparent tints.

Step 4: Pour and Finish with Care

Once your resin is fully mixed and evenly coloured, pour it into your prepared mould, surface, or project. Seal your work area and wear gloves to protect skin from stains. To achieve gradients or layered colour effects, pour in stages, letting each layer set slightly before adding the next. Work in thin layers to better control the colour effect and reduce the risk of pigment sinking or bleeding. Allow the resin to cure undisturbed per your product’s instructions.

Tips, Mistakes, and Troubleshooting

Take note of these practical tips: Transparent colourants show best in thicker sections of resin, while pastes and high-coverage liquids suit thin or patterned pieces. Avoid exceeding the recommended colourant percentage, which can soften cured resin or cause uneven setting. If colours appear cloudy, check for unmixed pigment or try adding resin in thinner layers. Unwanted specks or swirls often result from rushed mixing, so patience is key. Experiment with tiny test batches to perfect your colour mix before committing to a major artwork.
