Button quail morphs

[Rii]

Hi all!
I am extraordinarily bad at identifying button quail colour morphs so I’m hoping you good people would like to have a look at my newest quail and give your opinions!
Below are 3 birds (2 pics each). I’m most interested in the weird silver/brown combo. I have 3 like it and they all started out looking like plain silvers but after a few weeks starting going brown!
Also I’m assuming all 3 of these are female?? No rust feathers or bibs on any of them, although not sure how relevant that is for the silvery one

From top to bottom:
1. Golden pearl
2. Normal/wild type
3. Cinnamon
And yes, all 3 are female.

Thankyou!
How do you tell the golden pearl from the wildtype in females? I can see the pattern on the head is different (more of a dark cap on the wildtype) but the rest of the bird looks so similar to me I’m sure it’s just my untrained eye but interested to see what traits I’m overlooking
