Is this fish sick?

[Ab129]

Hi everyone, long story short I purchased this orange back fairy wrasse from LA.
The colors are a FAR cry from many photos I have seen of this fish. My specimens colors are muted, almost mottled.
Even though I am unhappy with his looks he is in my QT and if he is healthy, I don't plan on flushing him because he's not colorful enough. My only concern is if his appearance is due to some sort of illness.
He's currently in week 2 of Qt with a royal gramma and shrimp goby.
What do you guys think?

Give it time. Colors should return

That would be great but how does that work exactly?

Fish can change their colors based on mood.
