How to Get Transparent vs Opaque Colour Effects in Resin

← Back to How to colour resin with acrylics?

Whether you’re crafting jewellery, river tables, or decorative pieces, understanding how to achieve transparent versus opaque looks in resin is essential for striking results. Here’s a simple, practical approach to both effects.

Choosing the Right Colourants

To make your resin transparent and colourful, opt for transparent dyes or dedicated products like the Magic Crystal Transparent Resin Colour. These colourants blend fully with clear resin, producing a vivid, glass-like appearance suitable for crystal effects or mimicry of tinted glass. For an opaque effect, use high-coverage liquid pigments or pastes such as the Colourfun Liquid Epoxy Resin Colourant. These distribute colour evenly throughout the mixture, resulting in solid, non-see-through finishes.

Adjusting Intensity and Transparency

The level of opacity depends on how much colourant you add. For a stained-glass effect, start with a drop or two of transparent dye per 100g of resin and mix well. Gradually add more if a deeper shade is desired, but take care not to exceed manufacturer recommendations. To intensify opacity, add concentrated paste in small increments until you reach the desired coverage. Always blend thoroughly for even colour results.

When Transparency or Opacity Matters

Choose transparency when you want light to pass through, such as in lamp bases, jewellery, or layered art. Opaque finishes are ideal for bold, vivid statement pieces, hiding inclusions, or projects where complete coverage is needed. The right effect brings your creative vision to life and enhances the purpose of your resin project.
