What I have found in the web I like connaught green variant 1 a lot. Deep Brunswick green looks too much „green“ if you know what I mean. It is in my view a two fold task. First, which BRG do I like, Second does it fit a Morgan? For example I like Jag C Type dark green but will it fit a Morgan? CG Variant 1 seems to be a good match to your Morgan.
