you unscrew the face-plates, and either take a picture or describe what

I'd expect it to be:

1 Orange / White
2 Solid Orange
3 Green / White
4 Solid Blue
5 Blue / White
6 Solid Green
7 Brown / White
8 Solid Brown


Er, well then, you'd be wrong to expect that.

The TIA 568B standard (almost universal for UK structured cabling
installations) for an RJ45 connector is based upon the Western Electric
Colour Code, as follows

1. White/Orange
2. Orange or Orange/White
3. White/Green
4. Blue or Blue/White
5. White/Blue
6. Green or Green/White
7. White/Brown
8. Brown or Brown/White

In all cases where two colours are shown, the first colour is the main
colour and the second colour is the tracer (or stripe) colour.
