What color does yellow and lime make when mixed as paint?

A yellow close to Dancing-Lady Orchid (#DFFF00). Pigments subtract light, so the mix is darker and duller than either parent; exact results vary by brand and binder.

What do yellow and lime make as light?

A color near Yellow (#FFFF00). Light mixes additively, so overlapping sources brighten instead of darkening, which is why screens and paint disagree about the same pair.

What happens with more yellow than lime?

The result slides toward Yellow along the mixing curve; the live slider on this page computes the paint and light result at any ratio, with the hex code of every step.

What does yellow and lime make?

In paint, yellow and lime make a yellow close to Dancing-Lady Orchid (#DFFF00). Mixed as light, the same pair gives a result near Yellow, because light adds while pigment subtracts.

Theory

Why paint and light disagree

Pigments work by absorbing light: each paint removes part of the spectrum, so combining yellow and lime removes more light than either alone and the result darkens. Screens and stage lights work the other way. Each light adds energy, so overlapping them moves the result toward white. The slider above computes both models at any ratio: the paint result uses red-yellow-blue pigment interpolation, the light result uses additive blending.
