Boys vs Girls and Turquoise Pallids

[Rueae]

Turquoise pallids.
I've been looking at some pictures and most of the females I've been seeing around are very light compared to the boys.
Are boys just darker? Have bluer tails?
In general?
It seems to be a little difficult to find pictures.
Anyway, I really love this mutation and just wonder if I should wait for a boy or just go willy nilly for one that isn't sexed when the time comes.

Example of color in many female pictures I've found



Example of male



And in this one they both seem to be pretty matched, but the male has a bluer tail?



Is this just photography being a bit less than real life? Perhaps differently ages birds?
Are they really the same (sans ring, of course) or is the female a little washed out comparatively?

The pallid is probably the only primary mutation that occurs through the matings of cinnamon to lutino. A process of crossing over of chromosomes causes this effect. The offspring occur in two phases viz the lacewing( a dark phase) and the yellow head cinnamon (light phase) . These birds have been paired indiscriminately so as to cause the shades to vary. You will find dark birds in either sex. In my observations Lacewings paired to dark eyed birds darkens the shade of lacewing offspring.
Hope this helps

Thank you very much, I feel like I understand a bit better.
