That red dye, if in contact with the wire, eats it up like some sort of 
acid, you can literally pour the copper out of the ends where you've cut 
it in two, onto a clean sheet of paper, as a dark brown powder that 
looks a lot like rouge.

As a C.E.T., I've been battling with the cable failures its caused since 
the J.A.Pan company took over the two way radio we here in the USA call 
Citizens band in about 1969 or 1970.  That brought with them, the first 
of the J.A.Pan made microphone coiled cables, all of which had that 
bright red, almost magenta dye in the wire they used for Push To Talk 
control.  Its average life ranged down to 6 months in some cases. Even 
the truckers who depended on folks like me to keep them on the air 
noticed and happily paid 4 or 5x the cost of the J.A.Pan cable, for an 
American made cable.

I'm a retired old fart, be 84 in 3 weeks and I've been chasing electrons 
for a living and making then do useful work since around 1949, had a 1st 
phone since 1962, and been a Journeyman C.E.T. since 1972, so don't tell 
me about red being just a sata-1 slow cable.  You can buy them today, 
with a sata-III blurb on the bag, but it still only lasts 3 to 5 years. 
Black, tan, blue just fine, and I have these other colors in my other 5 
systems, some of which are as old as sata itself, but only one non-red 
cable has failed. And when cut in two, the wires were fine, but the gold 
flash on the connectors was gone, or never existed.  Cheap cable, came 
with the last WD drive I ever bought, and the drive itself was gone in 
less than 10k spinning hours. Seagates? Spin them up and replace them 
when they are too small for the job. The last one I pulled had 77,000+ 
spinning hours on it.
