Yep, colors are also just frequencies after all. Once you go below the visible/audible spectrum, you get infra red/infra sound and ultra violet/ultra sound above the spectrum.
Just like absolutely everything else, sounds are perfectly scientifically quantifiable, even the "magic".
Although when people use warm, cold and other adjectives to describe sounds, they tend to be a lot more subjective. Describing sounds with words isn't exactly an accurate science
For example, I hear a lot of sounds that are more reminiscent of old digital gear in "warm analog" soundset demos. "Warm" often seems to be connected to "nostalgic" instead of an actually warm frequency spectrum to many people.
