Winter Cool Deep with darker skin

I have darker skin and am a Winter Cool Deep. I used to think I was an Autumn Deep, but I recently found out I am a Winter Cool Deep. I haven't been wearing much makeup because I've been busy studying, but when I buy a cushion, shade 23 is my skin tone, and I do use 22 if I want a brighter look. However, since I am a Winter Cool Deep, should I use a yellow base or a pink base? Please recommend a cushion or foundation.
