Gigabyte B550 Vision are white. However, they're over your budget, with roughly costing $300. I'm not sure if this is because of low availability or other reasons. It just seems weird a B550 chipset costs that much.
Gigabyte also released their updated X570 chipset, calling it X570S. There's the X570S Aero, but I couldn't find the MSRP because it's relatively new.
