Maximum likelihood conjoint measurement of lightness and chroma
journal contribution
posted on 2023-06-09, 01:24 authored by Marie Rosanna Rogers, Kenneth Knoblauch, Anna FranklinAnna FranklinColor varies along dimensions of lightness, hue, and chroma. We used maximum likelihood conjoint measurement to investigate how lightness and chroma influence color judgments. Observers judged lightness and chroma of stimuli that varied in both dimensions in a paired-comparison task. We modeled how changes in one dimension influenced judgment of the other. An additive model best fit the data in all conditions except for judgment of red chroma where there was a small but significant interaction. Lightness negatively contributed to perception of chroma for red, blue, and green hues but not for yellow. The method permits quantification of lightness and chroma contributions to color appearance.
