Telephone Color Code

EDIT newer post with color image and also 568A/B located HERE 

Supprised that I did not post this earlier.

 For station wiring, you will either have wire that is green/red + yellow/black, or blue/white + orange/white

Line 1
Green = blue white
Red = solid blue
Line 2
Yellow = orange/white
Black = solid orange

Here is a run down of the colors for larger cable


For cables larger than 25 pair the wire is wrapped into binders, where the first 25 are wrapped in white, then the second in red, etc...

If you notice the first colors repeat, blue, orange, green, brown, slate. To make this easy to remember, all you need to do is remember the phrase "Bring Our Guys Back Safe"(Blue, Orange, Green, Brown, Slate)  To recall the order of the second color you just need to remember the phrase "Why Run Backwards You'll Vomit" (White, Red, Black, Yellow, Violet)
