How to Test Colour Intensity in Marble Resin Projects

Test Colour Intensity on a Small Sample First

When colouring marble resin, it’s crucial to test your chosen colour intensity on a small sample before working on your main piece. This simple step can help you avoid unwanted surprises and achieve a professional finish.

Why Sample Testing Is Essential

Different pigments and dyes interact with resin in unique ways, which can impact the final result. By creating a small test sample, you can check how your chosen pigment or dye mixes with the resin, how vibrant or subtle the colour appears, and whether the mixture cures as expected. Testing first means you can adjust the pigment ratio without risk to your main work.

How to Test Colour Intensity

Begin with a clean mixing cup and combine a small amount of resin with your selected dye or pigment, such as the “Renaissance” dye set. Add pigment gradually—1% pigment creates a translucent look, up to 5% gives a more opaque result. Mix thoroughly, pour the test sample, and let it cure fully. Assess the cured colour in different lighting before making any further mixtures.

When This Matters Most

Colour accuracy: For intricate marble effects or matching a specific décor, testing prevents costly mistakes.
Batch consistency: If you need to repeat the colour across multiple pours, a sample ensures you can match the mix each time.
Product compatibility: Not all colourants behave identically; testing with your actual resin and chosen pigment—like those from the Colourfun range—confirms proper blending and finish.
