Hi,
I think behavioral characteristics run in families but not necessarily by color. In my flock, some pairs produce many different colors with similar dispositions.
Here are some photos from this evening. Notice how well they posed for me (not). It was like photographing lightning. Still, I hope you will enjoy seeing how different they can be. I have labeled the coloring according to what I have learned and why.

Green greywing hen 'posing' face forward :-) next to a mauve cock. Note her pale cheek flashes compared to the mauve; also her body color is lighter than that of a normal green.

Another full-body-colored greywing; peek-a-boo; note dark cheek patches. Hard to see; but she is a deep sky blue.

Violet greywing; cheek patches and violet body color are half as dark as normal

Another green greywing; one might think it is a clearwing; but the cheek patches are half as dark as normal. A clearwing has the body color of a normal green; and this bird is a bit paler.

Cinnamon dominant pied; pretty bird with cheek patches and cobalt body color half as dark as normal; wings are brown.

English-style greywing cobalt with a golden-faced sky blue spangle in background for comparison of cheek patch colors; also he is lighter-colored than a normal cobalt His wings are gorgeous grey.

Note this bird's whitish wings, very light green color, and very pale cheek patches, they are whitish-lavender. I think this bird is a real dilute green, also called a 'yellow'.

This is my Merton's father, also with super-pale cheek patches; though he's a lovely green, he is much lighter than a normal dark green. I consider him to be a real dilute green (yellow). The cheek patches are lavender.
I hope you have fun looking at these pictures.
