You're also using the language of taste to describe tastes. "Warm" describes a thermal sensation, "bright" describes a visual sensation, and "sweet" describes an oral sensation. So "spicy" in regards to how a food tastes does have a very specific and single use meaning, as does "sour." "Warm" in regards to a tone means what exactly? What does "bright" or "sweet" mean? Can you at least identify which harmonics are present at what decibels for those tone descriptions, in your opinion?
Warm to me means slightly overdriven, with solid lows and present low mids, not a lot of highs - like a P bass or a J bass neck pickup, with flats, played with fingers through a nice old tube amp - which has nothing to do with Rosewood. Bright to me means a lot of highs present, not a lot of mids, and very clean amp voicing, maybe also played with a pick - trebly, like a Jazz bridge pickup with the tone up to ten and round wound strings through a solid state amp and EQ'd for treble presence - nothing at all to do with maple. I can get warm or bright, to my definition, with any bass. Sweet to me means absolutely nothing, other than "sweet bass tone, dude!!"
