What are Clearwings?
Clearwings embrace the Whitewing Blue series, and the Yellow-wing green series.
Whitewing Blues
Whitewing Sky Blue
Whitewing Sky Blue
This is the counterpart to the Yellow-wing Light Green, having no dark factor. They are used extensively by Clearwing breeders to improve size.
Whitewing Cobalt
This is the equivalent to the yellow-wing Dark Green, having one dark factor. Their deep body colour contrasting with white wings makes them ideal birds for the showbench.
Whitewing Mauve
The equivalent in the green series is the Olive green. These birds have two dark factors.
Unfortunately, they are not exhibited extensively, although there are some excellent examples around.
Adding the grey or violet factor to the whitewings will produce all the three colours with these colour "modifiers" added. Hence we obtain Light Grey, Medium Grey, and Dark Grey.
Similarly, with the violet factor added, we obtain Violet Sky Blue (a sort of "soft" cobalt colour),
Violet Cobalt (the "visual" Violet), and Violet Mauve.
Yellow-Wing Greens
Yellow-wing Light Green
Yellow-wing
greens are the Whitewing Blues’ counter part.
As
with Whitewings, Yellow-wings are recessive to every variety except yellows and
whites.
As
in all varieties, green is dominant to blue, therefore it is quite logical that
Yellow-wings are dominant to Whitewing Blues.
Yellow-wing
Light green.
This
is the green equivalent to the Whitewing Sky Blue, having no dark factor.
They
are not generally exhibited in large numbers, as there is not as much contrast
between the wings and the body colour as there is with the darker shades.
They
can however be very useful in adding size to Clearwings.
The
Yellow-wing Dark green.
This
is the green equivalent to the Whitewing Cobalt, having one dark factor.
These
birds with good deep body colour combined with very yellow wings are very
striking and used extensively on the showbench.
Yellow-wing
Olives.
Again,
the Yellow-wing olive green is the counter part of the Whitewing Mauve, having
two dark factors. These are also seen quite often on the showbench.
Adding
the Violet factor.
As
with Whitewings, the violet factor can be added to the three normal shades of
Yellow-wing, producing violet Light green, violet Dark green and violet Olive
green.
A
point worth remembering here is the fact that a Yellow-wing can possess the
violet factor without necessarily being split for blue.
We add the violet factor to our Yellow-wings quite often, and we have found that in general, we produce violet dark greens with deep body colour, without darkening the wings.
