New bike away goal weight

I know color really doesn't have much top do with a bike's performance, and a well practiced cyclist can be better at mechanical shifting than a rank amateur with electronic shifting; here's my question.
When I reach goal weight I can get a new bike. The one I really like had an awesome color scheme, and Ultegra Di2 disc and carbon hoops, another bike has mechanical Di2 disc and carbon hoops, but I'm not a fan of the paint? Should I get the higher level spec and paint job I longer or get the fully adequate mechanical with functional paint? Both frames are same level from same manufacturer.
