Still hope for Pullet??

[CoastChick]

5 Weeks old. Gold Sex Link bought from feed store and was decidedly darker (2 days post hatch) with a gold U shape on butt.
Now, the comb and wattles seem to have popped overnight and are a dark rosy pink. Much more light yellow feathering than my presumably female Buff Orpington.

Is there still hope for Luna to be female?

Light yellow? Looks white in the pic.
If it's a gold sex link it's a male. A female would be darker then the buff Orpington.
