This means you have PSCB-brakes which are covered in a layer of tungsten-carbide. Tungsten-carbide is about ten times harder than steel which means you will have approximately a tenth of the brake dust as normal steel brakes under the same circumstances.I have white ones and they don't get more dirty than my car.
