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]
