The wild-type colour is green with a yellow face, yellow and dark grey laced back and wings, a dark blue tail, and blue and black spots below the eyes.

Males have a blue cere (nose), hens have a brown one when in breeding condition, otherwise whitish. In babies, males have a bright pink nose (center and right in photo) and hens have a whitish one (top, left, bottom). Ino males keep their baby colour of cere, but in all budgies from 3-4 weeks and older, the deep righly-coloured cere on a male and the pearly whitish or tan cere on a hen will apply, regardless of the actual colour of the cere.

Males of the normal variety are grey with white on their wings, yellow on their tails, and a yellow face outlined in white and marked with an orange cheek patch. Hens are similar, but have grey shading on the face and grey lacing on the tail.

Males have a green back, yellow front, and turquoise face & shoulders & flight feathers. Hen have a smaller face patch, white-yellow in front of the eyes, and a green chest. Individual birds vary in how much red/orange they have on the chest and abdomen.

Males have a brown back with yellow lacing on the wings, a pink abdomen, brown towards the throat, and a blue forehead, shoulders, and flight feathers, and a turquoise rump. Females have more brown and less blue and pink, they usually lack the blue forehead completely. Mutations can be easily sexed by behaviour. Our favourite mutations are rosy opaline (pink back instead of brown), lutino (no brown or blue), and rubino (opaline-lutino combo).
