London Bridge doesn't have any support cables.
White and Light-blue, like the colours of the Argentine flag.
It is standard concrete color gray with white support cables and Sea Turtle friendly lights.
Officially steel but they are painted on a regular basis with red paint making them the same color as the rest of the cables on the bridge. Just google a picture to see for yourself.
They are red and white, or red and black for analog audio. Digital cables can be any color, as can HDMI cables.
