moshed;
If you have the ability to find a copy of OSPREY - VANGUARD book Battle for the Falklands - Ground Forces. It will have all the detail in the color plates you need.
If not then the next suggestion is surf the United Kingdom Ministry of Defence website for photos of uniforms. The DPM uniform (Disruptive Pattern Material)has been around for years and the colour scheme has remained the same. The GORE-TEX oversuits had been issued to the SAS and SBS during the Falklands in the DPM scheme.
I hope this helps somewhat.
Cheers;
Gregory
