What Is Value in Art?
Tonal value is the light-to-dark scale in a picture: how it works, six museum examples, and how to read it by squinting.
In studio language, value is how light or dark a patch of colour is, independent of hue. This guide sets out the value scale, grisaille and tenebrism, Ad Reinhardt’s blacks, photographic greyscale, the squint test, and the mix-up with saturation. Price uses the same English word and is out of scope.
