Columnidin is an orange red pigment, belonging to the 3-deoxyanthocyanidins^[1] found in red-flowered western-hemisphere gesneriad species such as episcias, columneas, sarmientas, and sinningias.

The columnidin is named after the gesneriad genus Columnea in which it is found,^[2] notably in Columnea hybrida.^[3]
