Drop red, yellow, blue, white and black paint one drop at a time to match a target color. Paints mix like real pigment, so blue and yellow make green. 24 stages plus a free lab.

Averaging RGB values on screen would give you gray, but this game approximates how paint absorbs and reflects light across wavelengths (Kubelka-Munk theory). So, like real paint, blue + yellow makes green, red + white makes pink and red + blue makes a muddy purple. It's a simplified model, so real paints can differ.
The difference between the target and your mix is measured with the CIEDE2000 color difference (ΔE), losing 2% per 1 ΔE. A ΔE of 2.5 or less, which means 95% match or more, is hard to tell apart by eye, so it counts as a success.
Finishing at or under PAR earns 3 stars, up to PAR + 2 drops earns 2, and more earns 1. Revealing which paints are used caps you at 2 stars, and revealing the ratio caps you at 1. You can replay cleared stages to improve your record.
