Do ratios change with different paint brands?

Yes, slightly. Pigment concentrations vary between brands. Use these ratios as a starting point and adjust. Always mix more than you need so you can replicate the exact shade.

Can I use these ratios for any paint type?

These ratios work well for acrylics, craft paint and emulsions. Watercolour and oil paints may need different approaches due to their transparency and drying properties.

How do I make a colour lighter or darker?

Add white to lighten (tint) or a tiny amount of black to darken (shade). For more natural results, darken with the complementary colour instead of black.

Why does my mixed colour look different when dry?

Acrylic paint dries slightly darker than it appears wet. This is called colour shift. Mix slightly lighter than your target and test on scrap material first.

Colour Mixing Calculator — Paint Ratios

Calculate paint mixing ratios to achieve target colours from primary and secondary paints.

Target Colour

Total Volume Needed

How We Calculate This

The calculator uses proven colour mixing ratios based on colour theory. Each target colour has a recipe of primary or secondary colours with specific part ratios.

Your total volume is divided proportionally across the component colours based on their part ratios.

These are starting points - always test mix small amounts first before committing to your full batch.
