Do I have to follow my personal color analysis?

Phew~ Just looking at the photos, there seem to be so many types. Personal color is difficult for me.

They say that personal color is finding the group of colors that suits each person based on the brightness and saturation of their innate eye color, skin tone, hair, etc.

I simply thought that fair skin meant cool tone and dark skin meant warm tone.

However, looking closely, it seems that it isn't necessarily divided that way.

So, if you use contrasting colors that don't match your personal color, does a person always look less vibrant? Then, before personal colors existed, didn't people judge based on style rather than color?

Do I really have to follow my personal color analysis?

I think my skin looks a bit yellowish, or maybe darker?

I usually prefer black, and for makeup, I mainly use red lipstick to create a natural, bare-faced look that adds vibrancy. I’ve thought this suits me well and have maintained it this way until now, but should I take a personal color test and change my style accordingly?

I'm wondering if I really need to follow my personal color analysis, since I'm afraid I might change what I've stuck to my whole life... haha.
