Abstract of the Disclosure Apparatus is provided for generating a set of color mixture signals associated with a set of coordinate axes from a pair of quadrature related color mixture signals associated with a different set of coordinate axes supplied from a source. Means are provided for determining the magnitude of the vector sum of the pair of quadrature related color mixture signals. Means are also provided from determining the angle between the vector sum and one axis of the set of coordinate axes associated with the quadrature related color mixture signals. A source of angle values provides the angles between the one axis of the set of coordinate axes associated with the quadrature related color mixture signals and the coordinate axes associated with the color mixture signals to be generated. Means are then provided for forming the algebraic sums of the angle between the vector sum and the axis of the set of coordinate axes associated with the quadrature related color mixture signals and the angle values from the source. Means are provided for producing trigonometric ratios associated with the algebraic sums. Finally, means are provided for producing the products of the magnitude of the vector sum times the trigonometric ratios. The products are the generated color mixture signals.
