FacebookHow to make coloured resin?
Step-by-step guide for vibrant, custom resin colours at home
Mastering the art of colouring resin opens the door to a world of creative possibilities, from striking jewellery to bold artwork and dramatic casting projects. This guide takes you through the fundamentals of making coloured resin, including material selection, technique, and expert tips for flawless, vivid colours every time.
What You’ll Need
- “Colourfun Set” – Liquid Epoxy Resin Colourant Set for Solid Colour Effects: Designed for artists and makers to add vibrant colour to transparent epoxy resin projects.

- Protective gloves, apron, and a well-ventilated workspace
- Mixing cups and stirring sticks
- Measuring scales (for accurate resin and pigment ratios)
Choosing the Right Colourant for Your Resin Project
Selecting the correct resin colourant makes all the difference for your result. Opaque pastes such as the Colourfun Set work beautifully for bold, solid colour, while transparent pigments like Magic Crystal Transparent Resin Colour bring stunning, glass-like clarity to jewellery and decorative castings. Always confirm compatibility with your chosen resin system for a flawless finish.
Step 1: Prepare Your Workspace and Materials
Work in a clean, dust-free environment before you start, as resin easily attracts dust and debris. Lay down protective covers, and make sure all your tools and moulds are silicone- or plastic-based and completely dry. Good ventilation is essential – always wear gloves and an apron to protect both your hands and clothing.
Accurate measuring prevents problems later on, so gather all your tools and check that your resin and hardener are within the recommended shelf life.
Step 2: Decide on Colour Style (Opaque, Translucent or Crystal)
Decide what level of transparency is required for your project: deep, opaque hues for bold artwork, or crystal-clear effects for jewellery and geode imitations. This choice dictates both the type of colourant and the quantity you use.
For bright, opaque finishes, a set like the “Colourfun Set” – Liquid Epoxy Resin Colourant Set for Solid Colour Effects or the “Colourfun” – Liquid Epoxy Resin Colourant 25-100ml ensures intense solid colours. For vibrant transparency and glass-like finishes, turn to “Magic Crystal” – Transparent Resin Colour 45ml or the “Magic Crystal” – Set of 5 Transparent Colourants.
Step 3: Mix Resin and Hardener Thoroughly
Combine the resin and hardener thoroughly in the exact ratio specified on your product label. Incomplete mixing is one of the most frequent causes of tacky, undercured resin. Stir slowly but deliberately, scraping the sides and base of the mixing cup for a few minutes until fully blended.
Avoid whipping air into the mixture, as excess bubbles will affect the final appearance of both clear and pigmented resin.
Step 4: Add Colourant Gradually and Blend Evenly
Add small amounts of colourant at a time to the mixed resin, blending well after each addition. Strongly concentrated pastes, such as those in the “Colourfun” – Liquid Epoxy Resin Colourant 25-100ml, require only a few drops per batch – be cautious, as adding too much can impact curing and saturation.
For glass-like effects, a transparent tint such as “Magic Crystal” – Transparent Resin Colour 45ml delivers clarity without cloudiness. Mix until the colour is fully uniform, with no visible streaks or lumps.
Step 5: Pour and Cure the Coloured Resin
Pour the coloured resin carefully into your prepared mould or onto your surface, slowly to avoid introducing more bubbles. Follow manufacturer instructions for layer thickness, as pouring too much at once can delay curing.
Protect the poured resin from dust and vibrations throughout the curing process. Wait the recommended time before demoulding or handling your piece for best results.
Tips, Common Mistakes, and Troubleshooting
Avoid using too much pigment, as this can interfere with the chemical reaction needed for resin to harden fully. Many colourants are highly concentrated – a little goes a long way.
Mix thoroughly to avoid streaks and patchy colouring. Use gentle folding motions rather than aggressive stirring to minimise bubbles.
If you want to customise colours, experiment by blending small amounts in a separate cup first before adding to your main resin batch.
If your result isn’t as vivid as desired, gradually build up pigment, but never exceed the recommended maximum proportion (usually around 5% of the total resin mass).
Expert Colour Blending for Unique Effects
Experiment with blending different colourants and layering for custom effects. Try combining shades from the Magic Crystal Set or mixing two opaque pastes for one-of-a-kind hues. For realistic gemstone effects, layer transparent tints with opaque undertones and control saturation drop by drop.
