Abstract
Opponent Process theory is a model of human color perception that predicts that there are four unique hues, with all others appearing as mixtures. An experiment was conducted to evaluate this model for its ability to predict the perception of qualitative relationships in single-variable quantitative series. Two such series were tested—“Balance” schemes where the categories represent varying mixtures of two distinctly different phenomena, and “Bipolar” schemes where the series divides into halves of differing interpretation. The results indicate that Balance schemes were most often associated with part-spectral hue progressions that fell between unique hues, while Bipolar schemes were associated with hue progressions that crossed a unique hue. This effect however is apparent only when value relationships are “double-ended” within the series.Keywords
