Two-colour process


Systems of colour reproduction in which the visible spectrum is divided into blue-green and orange-red regions for recording and presentation.

Although extensively used in early colour film processes, the inherent inability of two components to reproduce a satisfactory range of hues rendered all such systems obsolete when three-colour processes became readily available. 1
