What gender and color are these Coturnix quail?

[Appledaisy]

These are celadon Coturnix quail that are 4 weeks old. I am not sure if this color is feather sexable. Any ideas on sex? And any guidance on what this color is called? Thank you!!

The first one is not feather sexable. I think the second one is male.

Scarlet fee tuxedo (Rosetta roux with fee and white genes, decent chance it is female as roux is sex linked but not guaranteed) for the first bird, maybe a ginger on the second, could be cinnamon (red eyes) or a roux as well, not sure on base color, pharaoh maybe?
