Customisable Colour Intensity: From Opaque to Stained Glass in Resin

One of the joys of resin art is controlling colour intensity to perfectly fit your project, whether you want a completely opaque finish, soft translucent hues, or vivid stained glass effects.

How to Achieve Opaque Colours in Resin

For a solid, fully opaque look, choose highly concentrated resin colourants such as the Colourfun liquid colourant. Only a small amount is required to block light completely, offering strong coverage and vibrant shades. You can also blend black and white colourants for bespoke greys, or mix various hues for richer tones. Always add colour gradually and stir well—this ensures even coverage without over-saturating the mixture.

Creating Stained Glass and Translucent Effects

If your goal is to mimic stained glass or achieve a subtle, see-through finish, opt for transparent colourants such as “Magic Crystal” dyes. These are specially formulated to provide glass-like clarity in the cured resin. Begin by adding small drops and build up until the desired tint is reached, allowing plenty of room for light to pass through for that classic stained-glass look. Mixing within the same range lets you create unique, custom shades without losing transparency.

Tips for Fine-Tuning Colour Intensity

Start with less pigment—a little goes a long way with concentrated products.
For pastel shades, combine a touch of opaque pigment with clear resin for a ‘milky’ effect.
Test your blend in a small batch or on a sample piece to check opacity before committing.

When This Matters

Customising colour intensity is especially useful when crafting jewellery, home décor, or art panels that need to catch or filter light in specific ways. From bold statement pieces to subtle highlights, mastering this technique gives you much more creative control.
