Green is my favourite colour. I've ever owned 2 green guitars (not counting a bass), not at the same time, and I've owned over 60 guitars in my life. I guess green just isn't really a "guitar colour." Most of my electrics have been black, but maybe that's just because that is the colour they tend to manufacture guitars. Most of my "main guitars," though, have been red. And I'm a sucker for natural guitars.
So, I think my go-to's are either natural or red, generally.
