Does anyone know whats the difference between the purple and brown ground wire in the hid bulbs? i've seen the brown ones for 4300K bulbs and purple ones for the 6000K, what about 8000k?

do these just have different heat capacities? and what materials are they made from.

i've tried a search but nothin really talks about this topic.
