The legibility of colored symbology on a CRT map display was evaluated under simulated daylight. Experiment 1 tested the identifiability of the map's six line colors (White, Green, Yellow, Pink, Cyan, Red). Experiment 2 assessed the identifiability and legibility of the map's three point symbol colors (White, Red, Yellow). In each experiment, the intensity of the ambient daylight was varied from 5-13 times greater than the total (white) display luminance. Results showed that the legibility of most CRT colors will be degraded once the veiling luminance in the cockpit exceeds display luminance by a factor of 5-10. Smaller symbols and dimmer color (e.g., Red) become degraded once the veiling/display luminance ratio exceeds 5:1. Larger and more luminant features (White, Green) remain legible until the ratio exceeds 10:1. These results underscore the need to consider subtle luminance/chromaticity tradeoffs when using colors to code airborne displays.
