Blue-crowns are born with red coloring around the head, but blue-crowns are predominantly green, with dull blue coloring on the forehead, crown, cheeks, and ears in the nominate, but less blue in other subspecies. It has a ring of white featherless skin around each eye, though this is bright orange-yellow in wild T. acuticaudata neumanni.[4] The breast feathers may also be tinged with blue, though they are more commonly green to yellow-green. Closed wing coloring matches that of the body while extended wings show blue-brown, becoming chestnut on the outer flight feathers.
