When working with epoxy resin, achieving your desired colour effect—whether transparent, translucent, or fully opaque—relies on carefully controlling the amount of colourant added. Both beginners and experienced artists often ask: what percentage of pigment or dye is right for their project? This guide explores the ideal pigment loads and introduces you to high-performance resin products and colourants available at ResinPro UK, including “Colourfun” – Liquid Epoxy Resin Colourant 25-100ml – High coverage, “Colourfun Set” – Liquid Epoxy Resin Colourant Set for Solid Colour Effects, “Art Pro Deluxe” – Ultra-High Viscosity Epoxy Resin for Artists, the “Trasparente” Epoxy Resin Kit 800g + Mica Powder 10g – 10 Colour Variations, and “Sahara” – Mica Powder Pigment Metallic Motion Effect 10g / 100g.

Opaque vs. Translucent: How Much Pigment Should You Add?

Understanding resin colouration depends not just on colourant type, but also the percentage added by weight or volume. As a golden rule:

• Translucent/sheer effect: About 1% pigment or colourant by weight of the mixed resin gives a subtle, see-through hue—ideal for stained glass or ocean water effects.
• Opaque/solid effect: Up to 5% pigment by weight creates an intense, non-transparent colour. Exceeding this risks incomplete resin curing, so always follow product guidelines.

Both “Colourfun” – Liquid Epoxy Resin Colourant and the “Colourfun Set” – Liquid Epoxy Resin Colourant Set for Solid Colour Effects are designed to deliver high-impact colour at low dosages. Both are easy to blend and highly economical—just a few drops or grams transform litres of resin, helping you avoid pitfalls like streaks or cloudiness.

For metallic, pearlescent, or 3D effects, “Sahara” – Mica Powder Pigment Metallic Motion Effect 10g / 100g recommends usage: 5–8g per 1kg of resin. This achieves saturated, dynamic colour while preserving the resin’s crystal clarity for a translucent sheen.

Choosing an ultra-clear system like “Trasparente” Epoxy Resin Kit 800g + Mica Powder 10g – 10 Colour Variations ensures your chosen tint or effect stands out, while “Art Pro Deluxe” – Ultra-High Viscosity Epoxy Resin for Artists allows you to maintain sharp lines and avoid unwanted blending—even with maximum pigment loads for opaque results.

Comparison of Top Resin Colourants and Compatible Resin Systems

Here’s how our featured ResinPro colourants and resins support tailored opacity and transparency in your creative projects:

• “Colourfun” – Liquid Epoxy Resin Colourant: Long-lasting coverage and economical usage: a 25ml bottle colours 2–3kg resin. Perfect for both opaque and glass-like finishes—just adjust the drops per batch.
• “Colourfun Set” – Liquid Epoxy Resin Colourant Set for Solid Colour Effects: Intense, brilliant colours as pastes, excellent for blending custom shades, vibrant tints or thick, opaque coats—suited for resin rivers or large castings.
• “Art Pro Deluxe” – Ultra-High Viscosity Epoxy Resin for Artists: Maintains ultra-high viscosity for crisp, separate colours. Compatible with dyes and pigments (max 5% by weight), ensuring reliable curing from subtle tints to deep solid shades.
• “Trasparente” Epoxy Resin Kit 800g + Mica Powder 10g – 10 Colour Variations: Combines clear resin with versatile mica powder so you can experiment with opacity. Excellent for jewellery, table tops, and decorative art where depth and gloss matter.
• “Sahara” – Mica Powder Pigment Metallic Motion Effect 10g / 100g: Creates swirling, deep metallic highlights or translucent glazes. Use sparingly in transparent resin for lustrous, dimensional effects—and enjoy high lightfastness and thermally stable results.

All these options are cruelty free and vegan friendly, aligning with contemporary craft values.

Best Practices for Blending Resin Colourants

Getting your resin colour just right involves some basic technique:

• Always weigh (rather than eyeball) your colourant for repeatable, predictable outcomes.
• Mix pigment thoroughly to avoid streaks or patchiness.
• Start with a low percentage and add more if needed—once you’ve hit desired effect, note the measurement for next time.
• For mica powders and metallics, add incrementally, as these are intensely pigmented.
• Do not exceed manufacturer limits: over 5% pigment risks inhibiting proper resin cure, creating a tacky finish.

Products like the Colourfun liquid colourant and Colourfun Set are designed for easy to blend mixing, giving you seamless, professional-quality results every time.

Custom Colour Mixing: How to Achieve Special Effects

To create unique shades, blend different colourants from the Colourfun Set or introduce metallic and pearlescent effects with the Sahara mica powder. For greys or muted tones, mix black and white dyes or use grey shades of mica. In general, easy to blend products allow quick customisation—just keep pigment levels under 5% for full opacity, or at 1% for translucency.

If you’re shopping for complete solutions, the Trasparente Epoxy Resin Kit delivers everything for experimenting, including both resin and colourant. Or explore our Dyes and Pigments or Metallic pigments category to expand your palette.

For superfine art projects, Art Pro Deluxe resin ensures that custom colour blends remain vivid and sharp, supporting intricate geode pours, ocean waves, and contemporary art.
