What hair color did your Bias best rock?

I can't choose between blue

red

or purple

Jaehyun: black

Honorable mention to purple hair

Kun: Black (altho he is one of the few who can rock many colors and look good but black is still superior)

But he is also one of the few Kpop idols who can do blonde well

And honorable mention to blue hair

Kai: the turquoise hair was one of my faves

Renjun: Villain hair

I am going to say red hair when it comes to WJSN's Yeonjung.
