Choosing the right colourants for your resin project transforms the final result, whether you’re aiming for bold opaque tones, subtle tints, or gemstone-like effects. This guide is designed for artists, hobbyists, DIYers and professionals who want to achieve striking, durable and unique colour outcomes in their epoxy resin creations, including jewellery, art pours, river tables and more.

Understanding Resin Colour Options: Opaque vs Transparent

When selecting colours for resin, it’s crucial to distinguish between opaque, high-coverage effects and those that provide transparent clarity. Opaque colours—such as those in colouring pastes or certain liquid pigment ranges—are ideal for art pours, river tables, or where solid colour is required. Meanwhile, transparent colourants create glass-like or crystal effects, letting light pass through the cured resin for gemstone, geode, or subtle tinted finishes. Your choice will depend on the type of resin, project style, and the effect you wish to achieve.

Some colourants, including high-concentration paste and liquid forms, offer customisable intensity, meaning you can mix small amounts for lighter tints or use more for rich, opaque results. Sets with multiple shades give you flexibility for experimenting and blending your own unique colours.

Visual Comparison of Resin Colour Effects

Different pigment types yield distinct results: compare glass-like transparency from Magic Crystal with bold opacity from Colourfun pastes or liquids. Blending colours within a range allows for even more custom hues and unique effects in your resin creations.

Tips for Choosing and Using Resin Colourants

Pick your colourant based on the intended project outcome: use paste or high-coverage liquid for solid, opaque finishes, and opt for transparent colourants for glassy or gemstone-inspired effects. Avoid overloading your resin with pigment, as it may affect curing and clarity. Always blend colours thoroughly to prevent streaks or uneven tone. Experiment with mixing products within compatible ranges for custom shades and layered effects. For all your colourant options, browse our comprehensive Dyes and Pigments category.
