The only pictures I have of the real 4.7" guns are Black & White and none of my brief sources thought to mention colour. In most pictures the barrels don't look much different than the carriage, sometimes a little darker. I have read stories of British units going crazy with khaki paint during the Boer War, even painting mules, though that might be apocryphal, but a monochrome model was not going to cut it.

The original Britain's model came with a grey carriage and bronze barrel. The grey seemed plausible but I'm pretty sure the barrels were steel not bronze. Then I found a picture of the burst barrel of a 4.7 that supposedly was used in the Boer War and then at Gallipoli.

Now in Australian War Memorial
Black! There we are then. Now what about the crew? If this was an historical project I would have to do the sailors in standard army khaki with a naval straw hat. Borrrrrring! Luckily my old favorite History of The War in South Africa by James H Birch. (You can download it or read it on line, pictures included, here on openlibrary.org ) has a more attractive version seen below.

But I also found this on the net.
