I think the Blue Burst is classic and is what 'just looks right' because we are so used to seeing it in that color scheme.
I think the Morse standard can be a lot like some other classic double cutaway guitars in that it looks great with lots of different body/pick guard combos. The only limitation really is that the pickups are only offered in black (kind of ironic since Dimarzio offers a ridiculous amount of color options). I think if we added cream and or white pickup options the Morse could be even more stunning because certain color combos just look 'right' with non-black pickups.
I've been dreaming about a Morse standard in Lake Tahoe Blue with Tortoise Shell pick guard and Cream pickups...
I love my standard in Morse Blue Burst and know that I have one of the best made guitars in the world, I am completely happy knowing that alone. As I believe Steve himself said in an interview, you really only see your guitar when you take it out/put it back into it's case, as you only see the neck when you're playing anyway. I can still dream of the endless combos of color options though, right?
