I'm leaning more towards a Kronos color scheme with this, but not so elaborate as this is just a ship of the line vessel and not a command ship. Maybe a greenish grey hull color, with more grey than green, and with maroon accents.
Perhaps the green elements of the hull color ought to be in more of a sage green, rather than the traditional olive. In the low-lighting picture of the nacelle lighting, the green light makes the hull seem kind of sage-y, which I think looks pretty good.
Always like the Kronos One color scheme.
