Weaving versus blending

Abstract

In this poster we present the results of two experiments in which we seek insight into the fundamental information-carrying capacities of two alternative methods for encoding multivariate information using color: color blending and color weaving (1). We begin with a baseline experiment, in which we assess participants' abilities to accurately read numerical data encoded via one of six different single-hued color scales defined via joint variations in saturation and luminance from 6 base colors (fig 1). Figure 1: The six different color scales used in our experiment. To obtain the base colors, we selected six points evenly spaced about a circle of large constant saturation in the monitor gamut on a plane of constant luminance in the Lab color space (figure 2).
