'Warm' is inherently neither good nor bad. It descrobes a tonal balance that has more energy in the lower half--say, below 500Hz--than in the upper half. (A tonal balance having more high-frequency energy is called 'bright'.)
Warmth is absolutely a coloration, an error, but usually it sounds wonderful if not overdone. But warm becomes 'thick' rather soon.
So whether 'warm' is good or bad is truly a matter of opinion, but WHAT it is is rather commonly accepted.
