The canon artwork we have for them doesn't show much in the way of markings other than a hull number:

I checked Iron Wind Metals, but whoever painted that one up for Camospecs chose to go with Word of Blake colors, which isn't terribly helpful:

What Camospecs does have, though, is a
page for SLDF Fleet Asset paint schemes, which gives the verbal description and several examples, including this Vincent Mk 39:

That "light grey, dark grey and one other color" gave me enough leeway to go with something vaguely orca-like when I did
my own M-5 Caspar:
