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.

    I think green should also be there … but so should all the possible bi-colour combinations with the exception of green-and-yellow. It would make Table 51 very large though … the following are the recognised colours:

    Black
    Brown
    Red
    Orange
    Yellow
    Green
    Blue
    Violet
    Grey
    White
    Pink
    Turquoise

    So there are potentially 12+11+10+9+8+7+6+5+4+3+2+1 = 78 possible wire colours in single colour and bi-colour combinations
