How to Color Epoxy Resin: Mica Powder vs Pigment Paste vs Liquid Dye

Clear epoxy resin is a beautiful material on its own, but adding colour opens the door to metallic river tables, solid-colour countertops, translucent jewellery, decorative floors and countless art projects.

The difficult part is not deciding whether to add colour. It is choosing the right type of epoxy pigment for the finish you want.

Mica powder creates shimmer and movement. Pigment paste produces a dense, solid colour. Liquid solid pigment delivers an opaque, non-metallic finish and is particularly convenient for larger batches. Translucent dye adds colour while allowing light and details to remain visible.

This guide explains how to color epoxy resin, how the main pigment types differ and how to mix them without compromising your finished project.

Epoxy pigment comparison: Which type should you use?

There is no single “best” pigment for every project. The right choice depends on whether you want the cured resin to look metallic, solid, translucent or luminous.

Explore the complete Magic Resin pigment collection to compare the available finishes and colours.

1. Mica powder: Best for shimmer and movement

Mica powder is made from very fine mineral particles. When suspended in epoxy, those particles reflect light and produce a pearlescent or metallic appearance. The movement of the resin can also create swirls, waves and depth that remain visible after curing.

This makes mica an excellent choice for:

• Epoxy river tables
• Serving boards
• Coasters and trays
• Tumblers
• Resin art
• Metallic accents
• Marbled effects

Magic Resin mica powder generally creates an opaque appearance. Depending on the colour and the strength of the effect you want, approximately 50 to 125 grams may be used per gallon of combined resin and hardener. Always begin at the lower end and add more gradually. Some colours achieve strong coverage with less pigment than others.

How to mix mica powder into epoxy

1. Measure the resin and hardener using the ratio specified for your epoxy kit.
2. Mix the resin and hardener thoroughly, scraping the sides and bottom of the container.
3. Add a small amount of mica powder.
4. Stir slowly until no dry pockets or clumps remain.
5. Add more powder only if the colour is not yet strong enough.

For easier dispersion, blend the mica into a small portion of mixed epoxy first. Once it forms a smooth, lump-free mixture, stir it back into the main batch.

Do not judge the final result by the dry powder alone. A mica colour can look very different once it is wet, mixed and viewed at the full depth of the pour. A small test pour is the safest way to confirm the appearance.

2. Epoxy pigment paste: Best for concentrated, solid colour

Pigment paste is highly concentrated and produces a rich, opaque, non-metallic finish. Unlike mica, it does not create a pearlescent shimmer. It is a good choice when you want a clean block of colour or a strong contrasting accent.

Magic Resin epoxy pigment paste works well for:

• Resin jewellery
• Tumblers
• Coasters and trays
• Decorative castings
• Solid-colour accents
• Art and craft projects

Because the paste is concentrated, start with a very small amount. Mix it completely, inspect the colour and then add more only as needed. Adding too much at once makes the colour difficult to correct and may introduce more additive than the epoxy requires.

If pigment paste becomes firm during storage, warming the closed container in warm water for approximately five to ten minutes can help return it to a paste-like consistency. Keep water outside the container and away from the epoxy itself.

3. Liquid solid pigment: Best for opaque colour and larger batches

Liquid solid pigment produces a smooth, opaque colour without the shimmer of mica. Its liquid format makes it easy to distribute through larger batches, which is especially useful for floors, countertops and other projects where consistent colour from one section to the next is important.

Magic Resin Liquid Solid Pigments are suitable for:

• Flake flooring base coats
• Garage and basement floors
• Countertops
• River tables
• Coasters and serving boards
• Jewellery and castings

For floor applications, use one bottle per 1.5 gallons of combined resin and hardener. For projects such as river tables, coasters, serving boards and jewellery, approximately 2.5% pigment by epoxy volume is a useful reference point. This is roughly half a bottle per 1.5 gallons of combined resin and hardener.

For best results, pre-mix the liquid solid pigment with Resin Part A. Add Hardener Part B at the correct ratio and then fine-tune the opacity while mixing. Never change the required resin-to-hardener ratio to make room for the pigment.

When colouring a flake floor, choose a base colour that works with the dominant colour in the flake blend. For example, a light grey base complements blends such as Domino and Gravel and helps create even-looking coverage.

4. Translucent liquid dye: Best for transparent colour

Translucent dye colours the epoxy while preserving much of its transparency. Instead of hiding objects, wood grain or layers underneath the resin, it creates a tinted-glass or jewel-like effect.

This makes translucent pigment a strong choice for:

• Jewellery
• Decorative castings
• Coloured clear coats
• Encapsulated objects
• Layered resin art
• Projects where visual depth matters

A few drops can create a noticeable change. Add translucent pigment dye progressively during mixing until the desired intensity is reached.

Keep in mind that a translucent colour becomes darker as the pour becomes deeper. A shade that looks very light in a mixing cup can appear considerably stronger in a thick casting. Test the colour at approximately the same depth as the final project whenever possible.

5. Glow-in-the-dark powder: Best for special effects

Glow-in-the-dark powder can add a luminous effect to jewellery, signs, artwork and decorative castings. The pigment absorbs light and releases it gradually in darker conditions.

For the strongest result:

• Mix the powder thoroughly so it is evenly distributed.
• Use enough pigment to create the desired glow without overloading the epoxy.
• Test a small sample before committing to the full pour.
• Charge the cured piece under a strong light before evaluating it in darkness.

Magic Resin offers a 12-colour glow-in-the-dark mica powder set for special-effect resin projects.

How much pigment should you add to epoxy resin?

The correct amount depends on the pigment type, colour, project depth and desired opacity. There is no universal ratio that works for every colorant.

Use these Magic Resin product guidelines as starting points:

• Mica powder: Approximately 50 to 125 grams per gallon of combined resin and hardener, depending on the desired colour strength.
• Epoxy pigment paste: Begin with a very small amount and add gradually because the paste is highly concentrated.
• Liquid solid pigment for floors: One bottle per 1.5 gallons of combined resin and hardener.
• Liquid solid pigment for crafts and tables: Approximately 2.5% by epoxy volume, or about half a bottle per 1.5 gallons.
• Translucent dye: Begin with a few drops and increase gradually.

The safest rule is simple: start with less than you think you need. It is easy to make a colour stronger, but it is difficult to make an over-pigmented batch lighter without mixing more clear epoxy.

The correct order for mixing pigment and epoxy

Always follow the directions for the specific resin and pigment being used. A dependable general process is:

1. Bring the resin, hardener and pigment to the recommended working temperature.
2. Measure Resin Part A and Hardener Part B accurately.
3. Mix the epoxy thoroughly according to its instructions.
4. Add the pigment gradually and mix until the colour is uniform.
5. Scrape the sides and bottom of the container while mixing.
6. Check for streaks, dry powder or unmixed material before pouring.

An exception is Magic Resin Liquid Solid Pigment, which can be pre-mixed into Part A before Part B is added. This helps distribute the colour evenly, especially in larger floor-coating batches.

Work efficiently after combining resin and hardener. The epoxy’s working time continues while you are adjusting the colour.

Common mistakes when colouring epoxy resin

Adding too much pigment

More pigment does not always produce a better result. Excessive colorant can make mixing more difficult and may affect the epoxy’s appearance or curing performance. Follow the product instructions and increase the amount gradually.

Using a water-based household colour

Food colouring and other water-based products are not reliable epoxy pigments. Moisture and incompatible ingredients can cause cloudiness, poor dispersion or curing problems. Epoxy-compatible pigments are the safer choice.

Changing the resin-to-hardener ratio

Pigment is an additive. It does not replace resin or hardener. Always maintain the exact Part A-to-Part B ratio stated for the epoxy kit.

Failing to mix the pigment completely

Dry mica pockets, paste streaks and concentrated dye spots can remain visible in the cured piece. Mix slowly and scrape the full container until the colour is uniform.

Mixing too aggressively

Fast mixing can introduce unnecessary air. Stir steadily and thoroughly. If you are using a drill mixer for a large batch, keep the mixer head below the surface and use an appropriate speed.

Skipping the test batch

Colour changes with resin depth, background colour and lighting. A small test pour can prevent a much larger and more expensive mistake.

Choosing the right pigment for your project

River tables

Choose mica powder for dramatic movement and metallic swirls, translucent dye when you want to see through the river, or liquid solid pigment for a uniform opaque colour. Pair the pigment with a Deep Pour & Casting Epoxy Resin designed for the thickness of the project.

Countertops and table coatings

Pigment paste and liquid solid pigment create bold, consistent colours. Mica powder is better for marbled, stone-like or metallic effects. Use a Table Top & Coating Resin for thin surface applications.

Coasters, jewellery and moulds

Mica works well for shimmer, paste for strong solid colours and translucent dye for jewel-like clarity. Art & Craft Resin is designed for coasters, moulds and many small casting projects.

Epoxy floors

Liquid solid pigment is the practical choice for creating a consistent base coat across a large area. Select a colour that complements the decorative flakes and measure each batch consistently. Explore Magic Resin floor coatings for compatible epoxy, flakes and topcoats.

Frequently asked questions

Can I mix different epoxy pigments together?

Yes, compatible pigments can be combined to create custom colours and effects. Mix a small test batch first and record the quantities used so the colour can be reproduced in later batches.

Can I use acrylic paint to color epoxy resin?

Some makers use very small quantities, but acrylic paint is not formulated specifically as an epoxy colorant and may contain water or additives. For more predictable colour and curing, use mica powder, epoxy pigment paste or an epoxy-compatible liquid dye.

Does pigment change epoxy cure time?

An epoxy-compatible pigment used at the recommended amount should allow the epoxy to cure normally. Too much pigment or an incompatible additive can interfere with the result. Accurate resin-to-hardener measurement, thorough mixing and stable room temperature remain essential.

Can I add pigment to UV resin?

Only use a pigment that is compatible with UV resin, and add it sparingly. Very dark or opaque colour can block the curing light from reaching the full depth of the resin. Work in thin layers and cure each layer completely.

How do I prevent mica powder from clumping?

Add the powder gradually and mix it into a small amount of epoxy before combining it with the full batch. Break up visible clumps and scrape the sides and bottom of the cup.

Why does my cured colour look darker than it did in the cup?

Colour intensity increases with resin depth. The background and lighting also affect the final appearance. Test the colour at a depth similar to the finished project.

Final thoughts

Learning how to color epoxy resin becomes much easier once you choose the pigment according to the finish you want:

• Use mica powder for shimmer, metallic effects and visual movement.
• Use pigment paste for concentrated, opaque, non-metallic colour.
• Use liquid solid pigment for smooth opaque colour, especially in large batches and floor projects.
• Use translucent dye when clarity and depth should remain visible.
• Use glow-in-the-dark powder for luminous special effects.

Start with a small amount, mix thoroughly and make a test sample before the final pour. Those three habits will give you more control over the colour and help produce a cleaner, more consistent finish.
