I have a cool summer vibe, so how about brown hair?

I have a summer cool undertone, and I really, really want to dye my hair brown, but...

I know that brown colors really don't suit cool summer skin tones...

Even my skin turns a poop color when I wear brown clothes~~

I shouldn't dye my hair brown, right? ㅠㅠ I'll regret it, won't I?
