Added color refers to additional pigments that are painted onto a vase’s surface either before or after firing. It is a frequent
component of black-figure, red-figure, and white-ground vases. The most commonly added colors are matte white (primary clay
with minimal iron oxide) and matte red/purple (mainly red ochre), and occasionally added yellow. Other added colors are vegetable-based
greens, blues, and pinks, as well as gold (gilding), and were likely applied after the firing process.
