Inside Rolls-Royce's bespoke factory where 44,000 paint colors exist

For the ultra-wealthy, a mass-produced car won't do. Rolls-Royce has built its business on that premise, offering what it calls bespoke builds at its Goodwood factory. Customers can pick from more than 44,000 color options, commission hand-crafted wooden veneers, and order a ceiling dotted with fiber-optic stars that mimic the night sky.

The base price of a Rolls-Royce runs around $350,000 or more. The real spending happens on customizations. "When our clients interact with us, they don't need a car; they've typically got lots of cars. They want to create a masterpiece," Chris Brownridge, CEO of Rolls-Royce Motor Cars, told Business Insider.

Some customers still want more. They turn to third-party customization shops for further modifications. The process starts with pen and paper and ends on the factory floor.
