How to Create Custom Grey Colour Resin with Pigments

← Back to What quantity of powder pigments is needed to colour resin?

Looking to craft a unique grey shade in your resin project? With the right pigment combination and mixing ratios, you can easily tailor the tone—from light silvery greys to deep metallic charcoals—to suit any creative need.

Choosing Your Pigments for Grey Resin

To achieve a grey colour, you can use dedicated grey mica powder pigments such as those found in the “Sahara Set”—these powders lend a striking metallic effect and are well-suited for transparent resin systems. Alternatively, blend black and white liquid resin dyes for a neutral, non-metallic grey.

For a metallic sheen: Mix Sahara grey mica powder.
For a classic grey: Combine black and white liquid dyes incrementally until you reach your target shade.

Mixing and Quantity Guidelines

Accurate pigment measurement ensures both colour consistency and clarity in your resin work. As a general rule, use 8.5g (or 8.5ml if using liquid pigment) per 1kg of mixed resin for full, solid colour saturation. For powder pigments like mica, start with 5–8g per 1kg of resin and adjust for deeper or lighter results. Always premix the pigment thoroughly into part A (resin) before adding the hardener to help prevent clumping.

Achieving the Desired Effect & Adjusting Tone

To personalise your grey, you may adjust the ratio of black to white pigments or experiment with layering metallic powders for extra depth. Test a small batch before casting a full project—this helps ensure the resin cures as expected and that the resulting colour matches your vision. A mica pigment set provides the flexibility to create not only greys, but also custom tones to enhance different resin pieces.

When Custom Grey Really Matters

Custom greys are especially valuable for artistic pieces, modern home décor, and projects where the resin colour needs to complement specific design elements or match existing finishes precisely. Using a pigment set allows you to create harmonious effects across multiple works.
