Help finding undertone?

So up until now I always believed I had warm undertones, always liked golden jewelry better and thought most of my body looks warm. I always had difficulty finding a good foundation shade, they always seem too yellow on my face, I mostly just wear concealer for my dark circles. Recently I tried a new concealer (Dior Perfect Skin corrector) and among all the swatches I tried, the shade that most resembled my skin was 3C, so… a cool shade. That left me very confused. I think this is my favorite concealer ever, it just matched me so nicely. So I included a few pics of my skin in different lighting to ask you what you think my undertone really is. Thanks in advance!d
