How to Self-Diagnose Your Personal Color

What is Personal Color?

It is said to be a color theory analyzed based on the principles of color harmony and disharmony, which diagnoses the color that best suits a person and classifies them into four seasonal types.

Even after looking at personal color self-diagnosis methods, I still don't really understand it accurately. It feels like this is right, and that is right too.

Is there an easy way to self-diagnose? I am also curious about what my personal color type is.

I don't know my personal color well, and perhaps because of that, I feel like my style doesn't really stand out.

Of course, getting an accurate diagnosis from a professional would be the fastest way. However, that might be difficult for me, so I would appreciate it if you could let me know of an easy and quick method I can do by myself at home.
