What should I use for warm tones based on personal color?

They say you need to find your personal color and style yourself accordingly to make yourself stand out more. However, I don't know my exact personal color. Based on online self-diagnosis methods, I seem to be a warm tone. Since that is further subdivided into several categories, it seems difficult to find my personal color.

By any chance, what products should I use for a warm personal tone?

Which hair colors should I focus on to look better?

Also, what tones should I focus on for my clothes?

I have always worn only black and stuck to black hair. Does that not suit me?

Is that why my face always looks dull and dark...? Hahaha

Please recommend some colors that suit my warm skin tone.
