This could be such a dumb question, but how can you tell if a color is warm or cool?

I have warm skin tones so I seek out warm-colored clothing. But sometimes my assumptions about what is warm vs cool prove to be wrong. For example, I assumed burgundy was warm because it was reddish. I think of pink as warm, but some pinks are blue-based. And is there such thing as a warm blue? (I think yes— peacock blue is warm to me.)

Anybody have this figured out??
