I don't see how neutrality can be cold.
For something to be neutral, it has no warmth and no coldness, no sweetness, no dryness, thickness, thinness, wetness or rainbowness. etc.
Characteristics like these can have to do with the magnetism, voice coil, driver(s), diaphragm, filter, housing, nozzle or tip and so on, and are seperate to an FR graph.
