Hi Cazzie, cabin wall (and inside bulwark?) colours? Thats a very good question. I've been thinking about this but haven't decided yet! I think it would still be possible to change cabin wall colours at this stage!.
My deck is a light walnut, same for cabin walls. I used pear strips for inside bulkhead. I'm wondering if it would look better with a bit more contrast... darker-stained cabin walls? Or alternatively, painted walls?
I've searched a lot for definitive evidence but there doesn't seem to be any, giving us some freedom for personal preference. I oscillate between darker staining for the cabin/bulwark walls... and painting them a light colour... dirty white... cream... yellowish ocre (like Nelson's ships) etc. I think paint, even if light, would add a textural contrast with the deck.
