I hope you aren't suggesting running a blue pipe across to the
workshop for the cables to go in, blue is for water, black is for
power, yellow is for gas, some other colours including green, purple
and grey are for communication cables.

Out of interest, what would a 4-inch red pipe be used for? Never seen
that before AFAICR. One is being installed the length of my street at
the moment.
