Do bar tape this way?
There’s no functional reason not to do it, and it looks good. It’s different, but if you’re not scared by that, it looks better than all-the-same-color. Blue and green. Grey and blue. Yellow and green. You can wrap different sections different colors, and twine over the intersection to keep down the flaps. Add black to yellow and green, and everybody’ll think you’re a patriotic Jamaican. Remember, black touches yellow, but not green.
Get creative with bar tape, and personalize your bike. It’s only tape. You can change it quickly and cheaply if you don’t like it, but what’s not to like?
