How should I determine my personal color in relation to my skin tone, which suits winter?

It seems like you would understand it at first glance, but in reality, it is very confusing.

Even if I try to do draping, it isn't easy.

They say you just need to hold 'diagnostic cloths' of various colors, brightness, and saturation under your face and observe changes in your complexion, and I think that's about it. They say that through this process, you find the optimal color that gives a natural flush, makes blemishes less noticeable, and makes your impression look brighter, but I'm not really sure if that makes sense.
