Quantifying metamerism

Abstract

Metamerism can add an additional dimension to colour control systems. Different aspects of metamerism have been studied and discussed by many researchers. Computerised colorant formulations normally predict low metameric recipes, but the reliability of present measures of metamerism may be questionable as fresh aspects of colour appearance have been recently described. Chromatic adaptation and colour constancy are related phenomena. Studies in these fields are reviewed in this paper, which hopefully will encourage researchers to find a new and more effective measure of metamerism.

Visual measures of colour

“…The visual interpolation between atlas samples to determine the notation of colours not represented in the atlas is subjective and may differ between individuals. The phenomenon is known as 'observer metamerism' (Roy Choudhury and Chatterjee, 1992 ). 7.…”

Colour order systems

“…As any colour order system is composed of a limited number of physical samples, future inclusion of newer samples may be a problem. The assessment made by different observers may vary due to the phenomenon known as observer metamerism [13].…”

Metamerism and shade sorting

“…colour match failure with change of illuminating light source, adds a new dimension to the colour control systems. Different aspects of metamerism have been studied and discussed by many researchers (Roy Choudhury and Chatterjee, 1992). Computer colourant formulations normally predict low metameric recipes.…”
