How much colourant should I add to resin?

← Back to How to colour jewellery made with resin?

Choosing the right amount of colourant is key to successful resin jewellery projects. Too much pigment can cause problems, so it’s worth understanding the recommended ratios and best practices for mixing colour into your resin.

Recommended Ratios for Colouring Resin

For best results, do not exceed 5% pigment or colourant by weight of your total resin mix. Using more than this level may interfere with the curing process or result in a cloudy or less stable finish. Most high-quality colourants, such as those in the Colourfun Set, are highly concentrated, so only a small amount is typically needed to achieve vivid, even colour.

Mixing Techniques and Tips

Start by adding a few drops of your chosen colourant and mix thoroughly. Assess the resulting shade and gradually add more if a deeper or more opaque hue is desired—always staying within the 5% limit. Transparent effects can be achieved using clear resin dyes, while pigment pastes are better for solid, opaque results. Ensure the colourant is fully incorporated to prevent streaks or patchiness in your finished jewellery.

When This Matters Most

Strict adherence to the recommended colourant ratio is especially important when clarity, strength, or flexibility of your piece is required—such as in delicate earrings, pendants, or pieces where transparency is a key design element. Overloading with pigment can result in pieces that do not cure properly or lose their visual appeal.
