I'm having trouble deciding on a blush color for winter cool tones.

Hello, I'm a winter cool tone.

In the past, when I didn't know much about personal color and was ignorant, I used to just look for and use products with good reviews that many others used. But when I looked at my old photos, I realized that my makeup really didn't suit my face and looked strange.

So I took a personal color self-diagnosis online and found out I was a Winter Cool Tone!!

The blush is also just a famous product... I'm using a NARS product, but I'm not sure if this shade suits me well as a Winter Cool Tone. It's the NARS shade Sex Appeal. Is this a good color for people with Winter Cool Tone?

Am I using the right choice?

If this blush shade isn't suitable for winter cool tones, I would really appreciate it if you could recommend a blush shade that would be a better fit.
