Understanding exactly how much pigment to add to your resin is essential for achieving the precise colour effects you want—whether that’s a deep, opaque shade for a table, a subtle translucent tint for decorative pieces, or a shimmering metallic finish for standout art. This page guides resin artists, DIYers, and crafters in selecting the right pigment ratios and types for vivid and reliable results, whatever your epoxy project.

Comparing Pigment Types and Dosages for Resin Colouring

The ideal pigment amount for colouring epoxy resin depends on your choice of pigment and the desired finish. Highly concentrated liquid colourants are tailor-made for deep, even tints, requiring very little product to achieve strong results. For metallic, swirling, or pearlescent effects, powder pigments such as mica offer another level of dimension with their own usage guidelines. Both options have their own coverage recommendations, drying characteristics, and visual impacts. It is crucial never to exceed the manufacturer’s recommended pigment ratio—generally not more than 5% of the total mixed resin by weight—to ensure proper resin curing and maintain clarity or intensity.

Visual Impact of Pigment Dosage

See how pigment concentration transforms your resin project—from subtle translucency with just a drop, to vivid, solid colour at higher percentages. Use test panels or small sample pours to observe the effect before commencing your main project. Light, pastel shades require very little pigment, while deep or metallic colours use a higher but controlled amount for dramatic effect.

Easily blend colours for unique shades, always keeping within the recommended pigment-to-resin percentage for reliable curing and stable colour results.

Tips for Perfect Pigment Ratios and Colour Effects

Always start with a conservative pigment amount and build up gradually—resin can quickly become opaque or over-saturated, which may affect curing or clarity. For translucent effects, use 1% pigment (by weight) or less; for fully opaque finishes, 3–5% is sufficient for most concentrates. Avoid exceeding maximum pigment ratios to prevent incomplete hardening or cloudy results. For unique shades (such as greys), combine black and white liquid colourants, or add a touch of grey-toned mica for metallic depths. Always mix thoroughly to prevent streaks or uneven colour, and perform small test pours when trying new blends or brands.
