Adult male Superb Fairy-wrens are among the most brightly coloured of the species, especially during the breeding season. They have rich blue and black plumage above and on the throat. The belly is grey-white and the bill is black. Females and young birds are mostly brown above with a dull red-orange area around the eye and a brown bill. Females have a pale greenish gloss, absent in young birds, on the otherwise brown tail. The legs are brown in both sexes. Males from further inland and in the south-west of the range have more blue on the back and underparts.
