How to Make Grey Coloured Resin | Resin Pigments Guide

Creating grey resin is straightforward once you have the right pigments. Whether you’d like a traditional slate grey or a shimmering metallic tone, mixing the correct colourants makes all the difference. Here’s how you can reliably achieve beautiful grey shades for your resin art, crafts, or casting projects.

Choosing and Combining Colourants

To achieve a true grey tone in resin, start by using the Colourfun Set or Colourfun single-paste colourants. Simply blend a small amount of white pigment with black pigment until the shade of grey matches your vision. Adjust the ratio carefully—a little black goes a long way against white resin base, and it’s best to add pigment incrementally to gradually build the perfect tonality.

For a soft, muted grey, increase the white component.
For darker, more charcoal greys, gently increase the black pigment.

Adding Depth with Metallic Effects

If you’re after a sophisticated, shimmering look, consider mixing in a metallic grey powder alongside your existing grey blend. This adds a light-reflecting quality that can bring resin jewellery or decorative pieces to life, especially when used for surface coats or creative highlights. Begin with a basic grey and stir in small portions of metallic powder until you reach the desired depth and sparkle.

Tips for Consistent Colour Results

Consistency in mixing is key: always stir colours thoroughly into the resin before pouring to avoid streaks or uneven areas. When creating batches for larger projects, measure your pigment quantities carefully and note your ratios to reproduce the exact same grey each time. It’s also recommended to test a small batch before committing to your whole project—subtle colour variations can appear depending on resin type and curing conditions.
