The skull of Caihong has a length of 67.6 millimetres. It is low and elongated (superficially similar to that of Velociraptor), only slightly shorter than the femur.

Vertebrae

Caihong probably has ten neck vertebrae, thirteen back vertebrae, five sacral vertebrae and twenty-sic tail vertebrae.

Feathering and coloration

The fossilized feathers of Caihong showed similarity to a black iridescent color in extant birds. Other feathers found on the head, chest, and the base of the tail preserve flattened sheets of platelet-like melanosomes.

Caihong represents the oldest known evidence of platelet-like melanosomes.
