A free color mixing calculator for hobby paints
This free paint mixing calculator answers a simple question: if I mix these two paints in this ratio, roughly what color do I get? It is built for miniature and scale model painters who want to plan a custom color, stretch a palette, or find a midtone between two pots without wasting paint on trial and error. Pick a paint for A and a paint for B, slide the ratio from mostly A through an even split to mostly B, and the predicted swatch and its hex code update as you go.
The math blends the two measured colors in CIE Lab color space, weighted by the ratio you choose. That is the honest limit of the tool: real pigments mix subtractively, and every paint carries its own tint strength and opacity, so a strong color will pull a mix harder than the ratio suggests. Use the result to get close, then mix a small test batch and adjust. Below the prediction the tool also lists the nearest single pots across every brand, in case one already matches your target and saves you the mixing. It all runs in the browser, with no signup and nothing to install.
