A method of calculating a color blend for an output image is disclosed. In a fundamental form, the method comprises the steps of specifying a plurality of non-coincident points (x1, y1, z1), (x2, y2, z2), (x3, y3, z3) on a surface (1) to be subject to color blending. Next, a surface equation (Intensity=Ax+By+C) is derived for each color component from a pixel value (z1, z2, z3) of each of the points. The method then determines each output color component from the corresponding surface equation and a position of the pixel in the output image.
