Okay, folks, post your colour images/details here!
Now all the following images come from:

Thanks, Bernard - it's a ripper source!
(Apologies - my flatbed scanner seems to have committed suicide, so these are photos taken, at an angle to stop the flash glare obscuring all the image)
First up, Her Majesty's Royal Navy

HMS Good Hope, commissioned 1901

HMS Kent, commissioned 1903

HMS King Edward VII, also 1903
As paintings, they're probably very reliable colour sources. The red underwater, white waterline stripe, black hull, white upperworks and buff funnels are very consistent. But then I get this:

HMS Medea, commissioned 1889. As a colourised postcard or photograph one has to be suspicious, but this older ship appears to have either a white or light grey hull, with black bridge and funnels. Also notice the massive gold scrollworks surrounding the ship's crest on the bow. Anyone out there able to shed some light on this?
