I'm curious about a personal color analysis I can do at home!

I do feel like I'm a warm tone... but I really wanted to get a personal color analysis haha.

I'm really curious if there is a personal color diagnosis I can definitely do at home.

I thought it would be easier to do my makeup if I knew my exact tone through a personal color analysis.

Also, if I have an autumn warm tone, what is the most natural and best way to do my makeup?

Even if I feel like my makeup applied well, after going out and some time passes, it looks dull or red.

Since it changes all the time, I'm not sure of my exact tone... so I think I need a personal color analysis even more.

If I have a warm undertone, what kind of cosmetics should I use? I'm looking for product recommendations!
