I think I have a cool undertone. Please tell me which tint colors suit me.

I searched for "personal color self-diagnosis" on Naver and found out there is a method to check your color by the veins on your wrist.

Based on my self-diagnosis, I think I have a cool undertone. Please recommend some tint colors that suit cool undertones.

If you choose a tint color that matches your personal color, you will look a bit more vibrant, right?

But unlike my wrist, my face got a bit tanned in the summer so it looks yellowish. Still, I should use my wrist as the standard, right?
