Abstract
Observer metamerism (OM) is considered the disagreement of color matches due to different color vision between observers. It is a source of uncertainty for color specification and is essential for the design of imaging products. Many experiments have been conducted to quantify the degree of OM. In this paper, two color matching experiments were conducted to study the neutral white on two displays. Based on experiments, 95% ellipses of different SPs and observers were drawn on a*b* plane. Neutrality chromaticity of 2 displays was reported in terms of u’v’. The results of intra-observer and inter-observer variations were reported using mean color difference from a set of mean (MCDM) in terms of CIEDE2000 color differences. Intra-observer variation was calculated using MCDM between 8 repeat matchings. It was found that intra-observer MCDM was 3.9 ranged from 3.1 to 4.4. Inter-observer variation was calculated between observers under each luminance level or SP. It was found that inter- observer MCDM was 5.5 ranged from 4.1 to 7.3. Also, observer variation slightly increased when different SPs were involved.
