I removed the handles and spray painted it white.
I took a strip of Velcro and cut it in half to make in narrow enough to fit through the handle holes. I then sewed the two ends together, right sides both facing up.
The spray paint specifically said for all plastics and that priming wasn't necessary. It didn't love the dollar store plastic, it bubbled a little and chips off easily. Oh well it works and it matches my bike better than bright blue.
