How do I know if I have cool or warm undertones? Pink or yellow undertones?

Question

I have pale skin that is sunburned year-round. Usually, I would use a green concealer to get rid of the redness, but I've been using a good sunscreen, and my face is finally almost back to normal. Lately, I have been using only a little bit of the green concealer to cover up a few blemishes. My face has started looking really sallow this past week, and I actually needed blush. I have pale, slightly freckled skin, green eyes, and reddish brown hair. I also have blue veins on my wrists.

Answer 1

I would  try  pink  but do not really know  we need a picture.

Answer 2

I think its yellow!!

Answer 3

I am not a professional make-up artist, however, I will share what I learned from the girls in the beauty classes.

They had a guy look at his wrist, the veins in his wrist looked blue and slightly green because he had a yellow base tone in his skin.  Someone else had blue with a slight violet tinge which meant they had a pink base tone.  As how to tell if you're both, I am not sure. I think you'd probably be someone who can look good with both cool and warm tones (clothing and hair colour).
