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

A green close to Pestering Pesto (#00A028). Pigments subtract light, so the mix is darker and duller than either parent; exact results vary by brand and binder.

What do blue and lime make as light?

A color near Acapulco Aqua (#81ACAC). 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 blue than lime?

The result slides toward Blue 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 blue and lime make?

In paint, blue and lime make a green close to Pestering Pesto (#00A028). Mixed as light, the same pair gives a result near Acapulco Aqua, 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 blue 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.
