I've found variable results.  Some goes rigid and inflexible after
exposure, and will crack if you flex it.  For coax, the outer cover is
part of the characterisics of the cable, if that chemically deteriorates
it can affect performance (e.g. becomes permeable to water).  Not that
I'd expect to see trouble from ethernet use, but perhaps for comms.

I would have thought otherwise, but that seems the conventional wisdom.
Black will absorb more heat and cook itself in the sun, other things can
reflect it away much better.  Though is seems usual that the chemicals
in black plastic are more stable.
