I have been convinced by several people that the Tamiya colour FX79 (linoleum deck brown) is the correct colour/shade but I have my doubts now.
That looks like a good colour for the Cortiscene deck covering.
This is a type of linoleum used on a lot of upper decks of R.N, ships.
( An old E.R,A. told me once that they used it on the bridge areas, so that the officers didn't get "cold feet")
