Almost all car makers offer bright colours by default. In my driveway is a bright blue Subaru (it was hard to pick between the blue and eye-searing orange) and a bright copper coloured Suzuki. Mazda is becoming famous for their innovative colour options. Google "Nissan Micra colours" to see what even Japan's most conservative carmaker offers to those who care to look.
On selected models only :( E.g. Ford doesn't offer anything brighter than muted red on their Escape vehicles. They do have brightly-colored Mustangs, but nothing else.
Even Mazda doesn't offer them for all their vehicles.
