Apparatus for setting the colour point of a colour display device (20) comprises a video signal generator (50, 60) for generating an image on the display device, and a colour analyser (30, 40) for measuring the chromaticity of the image to produce digital coordinates corresponding to the colour point of the image on a chromaticity reference chart. The apparatus further comprises a computer system connected to the colour analyser (40). The computer system includes interface means (80) for reading the digital coordinates from the colour analyser, display means (10) for displaying a cursor at a point corresponding to the coordinates within a graphical representation of the reference chart, and processor means (50) for moving the cursor within the graphical representation in response to a change in the coordinates read from the colour analyser. The apparatus advantageously permits rapid adjustment of the colour point of a display device to a desired value with a high level of measurement repeatability. Any re-calibration of the apparatus can be performed by adjusting a set of digital values stored in the computer system. <IMAGE>
