Can independent dimensions of brightness and hue be used in a combined digital information code? This issue was addressed by developing 2 color-coding systems and testing them on informed and naive participants in signal beam detection and classification experiments for simulated sonar displays. Each coding system's results showed both groups efficiently used encoded information that varied simultaneously along the 2 dimensions of brightness and hue. Findings support the proposed procedures for developing color information codes and the validity of such information codes across different populations. Applied significance of these results is provided by the test of principled methods of color-code construction and the demonstration that extending the information content of user interfaces beyond 1 dimension is feasible in practice.Information-processing user interfaces, such as air-traffic control systems and automatic banking machines, encode information using salient perceptual attributes such as gradients of brightness or color and varieties of icons and alphanumerics. Much research on color use in digital information displays has focused on error rates and search time for targets (symbols or icons) when color is added as a target feature (Christ, 1975; Donderi, 1994; Nagy & Sanchez, 1990, 1992). Guidelines exist for the number of hues used for targets and backgrounds, the use of luminance and saturation to improve perceptual segregation of colors, and effects due to ambient light conditions (Van Orden & Benoit, 1993). However, there remains some uncertainty regarding the conditions that make color a good choice as an independent, nonredundant coding dimension, and no guidelines exist for the applied use of multidimensional information codes. The present study explored the feasibility of two-dimensional hue–luminance codes and the use of color beyond a simple redundant code in a specific display format in which meaningful information is defined statistically as opposed to iconically. To do this, we pursued three goals:(a) modeling observer performance using ideal-detector theory,(b) developing two-dimensional information codes and meaningful methods of quantizing and encoding information, and (c) conducting empirical tests of implemented codes for gradient intensity signal applications.
