The crucial importance of the light source to successful colour matching can now be quickly and emphatically demonstrated with the Munsell Matchpoint Metameric Colour rule available from Macbeth. Operating as a slide rule, it provides quantitative evidence of the degree of metamerism — colours apparantly matching under one lighting condition mismatching under another — which is a prime consideration to those involved in making critical colour matching decisions. In addition, it can be used to compare the colour vision characteristics of people when used under a common light source.
