Personal color analysis… I’d like to try a self-diagnosis at home. How should I start?

Lately, I'm worried because I keep getting confused about what my personal color is every time I do my makeup.

I was even more confused because I heard a lot of people say that I look like a Summer Cool on some days and a Spring Warm on others.

At the shop Personal Color Diagnosis I was thinking about getting it done, but there are many types and the cost is quite high, so I want to check it myself at home to some extent first.

I looked it up and found that personal color types are divided into Spring Warm, Summer Cool, Autumn Warm, and Winter Cool, but just looking at the descriptions, I couldn't really tell which category my face was closest to.

My face tends to turn red easily, so even just changing my lipstick can completely change my appearance. That is why I find self-diagnosis more difficult.

Just in case you want to do something simple at home Personal Color Self-Diagnosis Are there any ways to try it out or any good tips for comparison?

Whether it's better to view it in natural light or test it against clothing colors... I would appreciate advice from those who have actually tried this.

Also at the shop Personal Color Diagnosis If anyone has received one, I would appreciate it if you could let me know what criteria I should use when choosing.

I think this will be helpful to those who are confused like me.
