Has anyone had a personal color analysis done?

Whenever I buy cosmetics, I often find that I buy them because they look pretty, but they don't suit me when I actually apply them.

Personally, I find lip color the most difficult, especially.
I thought coral suited me well, but on some days it looks completely dull.

I'm curious if getting a diagnosis really makes choosing clothes or makeup easier.

Self-diagnosis isn't easy, so I'm thinking of getting a professional test if I get the chance.
