6. In a graphics language interpreter that accepts commands indicating both device-dependent and device-independent color specifications, wherein the graphics language interpreter converts the device-dependent and device independent color specifications to internal color specifications before rendering, a color conversion method comprising the following steps: implementing a first pipeline for device-dependent color specifications, wherein at least the following steps are performed in the first pipeline: converting the device-dependent color specifications to internal color specifications using conversion acceleration hardware; applying transfer functions to components of the internal color specifications in response to graphics language commands that specify such transfer functions; implementing a second pipeline for device-independent color specifications, wherein the second pipeline performs steps comprising; converting the device-independent color specifications to device-dependent color specifications using a color rendering dictionary; passing such device-dependent color specifications into the first pipeline for further processing, wherein such further processing includes the step of converting the device-dependent color specifications to internal color specifications.
