Why are there two results?

Paint and light mix differently. Paint is subtractive: combining pigments removes light, so blue and yellow make green. Light is additive: combining beams adds light, so red and green make yellow. The tool shows both.

Is the paint result exact?

No. Real pigments vary by brand, binder, and ratio. The paint result uses a standard computational model and is a screen approximation of physical behavior, labeled as such, not a lab measurement.

Two kinds of mixing, one tool

Ask what you get when you mix blue and yellow and the honest answer is: it depends what you are mixing. Pigments are subtractive. Each one absorbs part of the spectrum, so stacking them removes light and blue plus yellow lands on green. Beams of light are additive. Each one adds to the total, so red plus green light makes yellow, and all three primaries make white. Most mixers pick one model silently; this one shows both so you can see the difference.

Drag the ratio slider to move between the two source colors, and the tool names the result as it changes, so you are not left staring at a bare swatch. It is useful for planning a paint blend, understanding stage lighting, or just building intuition about how color behaves.

One caveat we state plainly: the paint result is a computational stand-in. Real pigments differ by brand, binder, and how much you use, so treat it as a close screen approximation of physical behavior rather than a guarantee. The light result is exact for screen color, which is itself additive.
