The importance of Custom Colour Mixing.

Every project is different. Light in a room, the surface under resin and your vision as an artist has a contribution in how your final piece will appear. Ready-made colours are not always able to reflect the exact effect that you desire, custom mixing guarantees:

• Personalization: There are no two alike.
• Precision: Recreate current decor, brand colours or natural colours.
• Creativity: Discover exotic shades and mixes that are not part of the usual range.

Materials You will Need

before you start, prepare the correct pieces of equipment:

• Epoxy resin / hardener you can select a high quality, clear base
• Colorants: liquid pigments, powdered pigments, pastes or alcohol inks.
• Mixing cups & stir sticks
• Pipettes or droppers to measure the pigment accurately.
• Personal protective equipment gloves, apron and mask.
• Test surfaces small silicone moulds or sample boards on which to test colours before investing a lot of money in a large project.

Types of Colorants for Epoxy

Different pigments have different behaviours. Here is a quick breakdown:

1. Liquid Pigments

Liquid form, good with homogenous colours. Ideal in the case of translucent or opaque effects.

2. Pigments in Powdered form (Mica powders)

Give a glossy metallic or pearlescent appearance. Liked jewellery and river tables.

3. Alcohol Inks

Produce dynamic, fluid effects and patterns. More frequently applied to abstract works of art.

4. Pigment Pastes

Deeply rich, really saturated, colours. Exceptional with intense, solid paints.

Pro Tip: Never use pigments that are meant to cure epoxy resin as they will not cure.

How to mix custom colours step by step:

1. Start with a Clear Base:

Combine epoxy resin and hardener as it was instructed by the manufacturer. Always make sure it is mixed well prior to the addition of pigments.

2. Choose a Primary Color:

Choose your base colour, this will be the base of your mix.

3. Add Pigments Gradually:

Start small. Add in a drop or pinch and mix. Keep in mind a dark or saturation can always be brought down or made stronger, but an already saturated mix is difficult to de-sat.

4. Test Samples:

Use a little and pour in a silicone mould or on a clean surface and allow to dry. After being cured colours become darker or brighter.

5. Adjust the Shade:

Make your changes using the colour wheel:

• To darken: add a bit of black or a darker complementary colour.
• To lighten, add in either white or transparent base.
• To neutralise: add little of the opposite colour.

5. Record Your Formula:

Record the precise quantities (drops, grammes or scoops) of the shade that you can reproduce in the future.

Following the Colour Wheel.

Your friend in resin art is colour theory. A basic color wheel helps you:

Blend harmoniously: Mix adjacent colours (e.g. blue + green) to achieve natural blends.

Make contrasts: Complementary colours (e.g., red + green) will have bold effects.

Add or remove tones: Add or remove little bits of warm or cool tones to get the piece into the desired mood.

Troubleshooting Common Issues:

Color too dark?

Add more opaque epoxy or whiten with white paint.

Color too dull?

Add a grain of mica dust or a bit of a matching bright colour.

Uneven mixing?

Test and scrape sides of the cup so that there are no streaks.

Unexpected curing color?

Always do a test sample. Certain pigments undergo slight alteration on curing.

Suggestions on Consistency and Professional Performance.

• It is always good to mix in small test batches before getting yourself into a huge pour.
• Repeatability Use accurate measurements.
• Label and store remaining resin samples to use at a later date.
• Add depth by using transparent and opaque colours.
• Do not excessively saturate epoxy with pigment (generally not more than 5-7 percent of total mix), because this can retard the curing.

Creative Effects You Can Try

• Ombre Blends: Gradually moving between two colours.
• Marbling: Blend colours softly to resemble a stone.
• Pearlescent Depth: Apply mica powders to give a shimmer and multi-dimensional effect.
• Translucent Layers: Construct layers with tinted resins, which are slightly coloured.

Conclusion

Mixing of epoxy of custom colours is an art and a science. With the correct pigments, equipment and some practise your creations with resin can be truly spectacular and will take your projects to the next level. Keep in mind: be patient, precise and creative. Next time you make a batch of resin, then you need not be afraid to experiment, you can make your own ideal shade by combining two or more colours.

Mix boldly, pour confidently, and let your colours tell the story of your creativity.
