- Abstract
- This report is the final report on the development and field testing of an inexpensive color calibrator for the standardization of the Weather Intensity Level (WIL) colors used in theFAA's Radar Remote WeatherDisplay System or RRWDS. The report covers the field validation of the color calibrator and, as an end product, the construction of a tentative look-up table that identifies whether the six WIL colors are within acceptable limits. The look-up tble is tentative due to the small (5) number of field sites visited. The development of a color lookup table finalizes the validation of the color calibrator as a useful tool for calibrating the WIL colors used in RRWDS. Moreover, the color calibrator can be used to calibrate the colors of other tricolor display systems, provided an appropriate lookup table is developed. In addition, this report includes a general review of significant literature on color-coding, since RRWDS color codes weather information. The report presents first-of-its-king objective data on the effects of ambient room lighting on colors used in a self-luminous display. The effects were chromaticity shifts due to the presence of veiling reflections or glare from the face of the CRT console. This report may, accordingly, have significant impact on the design of building environments where color-coded CRT's are to be used.
