- Violet Factor
the grey factor. The violet factor is hard to detect, especially on yellow-based budgies.
If you look closely though, you may see a violet tinge on the body feathers around the feet and vent (budgie's poophole). True violet colour only shows up in sky blue budgies with one dark factor (cobalt blue budgies). If they carry the violet factor, they will also have a violet tinge in the body feathers near the feet.

- Dilution (colour is washed out)
- greywing budgies have grey markings on their head and wings (normal budgies have black markings there) + the body feather colour is about 50% diluted.
- Full-body-colour greywing budgies have the same markings as normal greywing budgies, but their body feathers have a brighter colour.
- Clearwing budgies have very light or no markings at all on their head and wings, and the body feathers are brighter.
- Dilute budgies are washed out from head to toe. The head and wing markings are barely visible and the body colour is 80% diluted.
