ABSTRACT:
Apparatus for generating a two-dimensional coloured display in which there is a variation of colour across the display in a predetermined manner, the colour of each pixel in the display being defined by one or more colour components. The apparatus comprises, for each colour component, a memory for storing a pair of gradation curves (X(i), Y(i)) representing the variation in intensity of the color component in orthogonal directions X, Y across the display; a monitor; and processing apparatus. The processing apparatus determines a resultant colour component value V(i,j) for a pixel to be displayed at a location (i,j) on the monitor in accordance with the following formula:
