The male Turquoise Parrot is bright green above, with a turquoise blue crown and face. A brilliant two-tone blue band around the bend of the wing contrasts with a dark, brick-red shoulder patch. Its underparts and tail edges are a rich yellow. The female is similar, but not as bright, with a whitish facial mask, no red on the wing, and a pale wing stripe. Old birds of both sexes may have orange underparts.
The Turquoise Parrot is similar to the Scarlet-chested Parrot, Neophema splendida. It is the females which could most easily be confused, as the males are more distinctive. The female Scarlet-chested Parrot has a more extensive cobalt-blue face than the female Turquoise Parrot.
