Green Budgies:   The Australian light green bush budgie is the ancestor of all Budgies, and the many color mutations that occurred later on in captivity  are responsible for the wide array of Budgie colors we have now.

Blue Budgies: The Blue Budgie comes in three shades: Sky Blue, Cobalt Blue and Mauve.  The  mauve might be mistaken for a grey bird, but mauves have dark blue cheek patches and tails, while grays have silver cheek patches and black tails.

Yellow Face Budgies: The yellowface is a ground color mutation. Yellowfaces have their yellow ground color diluted and restricted to certain areas of their body.

    Yellowface type 1: These birds can be blue (all shades), grey or mauve but they their heads, tails and tip of the wings are yellow.

    Yellowface type 2: These birds can also be blue (all shades), grey or mauve but the light yellow color is spread all over their body and not restricted in certain areas like type 1. Their original body color looks tainted in light yellow instead of being pure.

Opaline Budgies: Opaline is a mutation that changes the pattern on the Budgies wings. Instead of the regular striping, opalines have faint markings on the head and a "V" shaped patch of their boy color on their backs, just above their wings. Opalines come in all colors, since it's a wing pattern mutation and has nothing to do with body color.

Spangle Budgies: Spangles come in single and double factor. Double factor spangled birds are either all yellow or all white with dark eyes and an iris ring. Single factor spangles only have their wing pattern changed by this mutation, and instead of the feather being black and edged with the ground color (white or yellow), the feather becomes of the ground color and edged with black. This makes a very particular pattern almost pearly in appearance.

Grey Budgies: Both blue series, and green series Budgies can inherit the grey gene and their color would change due to its presence. All Budgies with the grey gene can be identified by their silver cheek patches, instead of dark blue and their black tail instead of blue. In the blue series, the Budgie looses its blue body color to a grey shade, and in the green series, they acquire a particular shade of olive green. Green series Budgies with the grey gene are called grey-green Budgies.

Dominant Pied: Pied Budgies have random patches of their ground color (yellow or white), replacing their wing markings

Recessive Pied: Recessive pieds  have the white or yellow patches replacing their markings and body color, but they lack the white iris ring. The amount of ground color patching can be very different with each Budgie

Dark Eyed Clear Budgies: Dark Eyes Clear (DEC) Budgies are pure white, yellow or cream birds. They look exactly like Ino birds, but they have black eyes instead of the ruby red eyes Inos have.

Greywings, Clearwings, Dilutes: The greywing: This mutation reduces the black markings to dark grey, and the body color is also diluted to a pastel shade of the original color.  The clearwing: Clearwings find their wing markings reduced to a very light grey, but their body color remains at full strength. the Dilute: Dilutes have both the light grey wings and the pastel body color.

Cinnamon Budgies: Cinnamon Budgies have light brown wing markings instead of the black.

Ino Budgies:  Ino budgies come in three colors: Albinos (all white with red eyes), Lutinos (all yellow with red eyes), and yellow face inos (light yellow, cream color with red eyes). When inos have the cinnamon mutation too, they are called Lacewings. Lacewings look identical to other inos, except that the original black markings of normal budgies is still visible on Lacewings in a faint brown version.

The Anthracite Budgie: These dark, almost black birds are not the result of the common grey gene, but it is the Anthracite gene that causes their feathers to darken into that stunning shade of grey.
