I'm not a fan of the colored cable housing. I would personally chose to keep that black. Personally, I prefer bikes to have subtle hints of color addition and I feel that the colored cables is just a hint to much. Its like you dont know what else to do with your bike so you just through on some color. (When I say you, I dont mean YOU, I mean someone in general).

Your red option looks unbalanced to me. I think a better red choice would be red hoods with red saddle.

ultimately I think White hoods with a white saddle would look best. But thats just my thoughts.
