Is the self-diagnosis method First Color correct?

After seeing the topic on personal color, I tried a self-diagnosis myself before writing this post. However, I'm not exactly sure. Using photo method #1, I seem to be a cool tone, but using photo method #2, I seem to be a warm tone.

I’ve lived my whole life thinking I had a warm skin tone. Aren't cool tones supposed to have fair skin?

I just thought of personal color as the easiest method that others think of.

I used to think simply that if your skin is dark, you're a warm tone, and if your skin is fair, you're a cool tone.

However, if you look into personal color in detail beyond just cool tones and warm tones, it is divided into many other colors.

Personal color seems to be a really difficult thing.

I have a rather dark skin tone. I'm confused by that self-diagnosis method. Am I really a warm tone?
