Island Blue Pearl Nail Polish? And flashing cruise control

Just noticed a small paint chip on my island blue pearl 2017 Impreza. Has anyone sought out bright blue nail polish for this kind of situation? I'm worried about rust if I don't do anything. Also it'd be pretty cool to have nails that match the Bluebaru :)

Unrelated, does anyone else have the bug where your cruise control will periodically start flashing and becomes unusable? I had my software reset/updated back in June but it didn't fix the issue. :(
