Red & Yellow & Pink & Green...

Zoomup

Purple & Orange & Blue. Singing a rainbow is fun.

What does B.S. 7671 say we can use these colours below for?

Brown, Black, Red, Orange, Yellow, Violet, Grey, White, Pink or Turquoise?

The combination of green and yellow is sacred and is to be used for specific safety purposes only.

    Except that GNYE (and YEGN) tracer colours look very different to 60/40 % bi-colouring.

    Trace colouring is a dab every few mm, whereas bi-colouring is part of the extrusion.

    Presumably the examples of the 25 pair Telco cable shown as 18 and 43 are only used for E.L.V. telecom cables and not L.V. protective conductors.
