A single scale 3-field instrument for visual colour grading by direct comparison between the sample and Lovibond glass colour standards housed in a pair of discs. The advantage of a 3-section field of view is that the sample and two consecutive glasses on the colour scale are viewed simultaneously, making it easier to achieve the optimum colour match.
