Body Color: Clearwing is a slightly diluting mutation. A Clearwing budgie will have an even shade of up to 10% diluted body color (body color will vary depending on whether they are green or blue, and if they have any dark factors) on their chest, breast and rump where it will be the darkest.

Head Barring Wing And Throat Spot Markings: Light grey with a yellow or white edge (depending on body color, the lighter the wing markings the better) with light grey throat spots.

Cheek Patches: Violet

Main Tail Feathers: Light grey or yellow

Feet And Leg Color: Blue or grey

Eye Color And Iris At Maturity: Black eyes with white iris.

Mature Adult Cere Color: Medium to deep blue in males,. Light blue/white to tan in females depending on if they are in breeding condition

Genetic Information: With the clearwing both males and females can be split for this mutation, but two copies of the gene (one from the father, one from the mother) must be present for a visual clearwing.
Clearwing is recessive with the exception of greywing and dilute. Clearwing, greywing and dilute are all varieties of the same mutation. Clearwing and greywing are co-dominant, meaning that when combined they make the composite mutation of fullbody greywing. Clearwing is dominant to the dilute mutation.

Cheek Patches And Main Tail: Depth of color in tail and cheek patches will vary with the dark factors a clearwing has, as you can see in the above link to tail and cheek patch photos.

Body Color Suffusion: The body color should not be on the head or wing markings of a well marked clearwing, with the exception being if they are also opaline.
