A Test for color appropriateness and color selections in multimedia design for color deficient observers
Abstract
Fifteen color normal and dichromatic observers participated in a CRT
image display study conducted via the Internet at the The Rochester
Institute of Technology. The groups consisted of three color normal and
twelve color deficient observers. All observers were given identical visual
tests. The tests, investigated one factor consisting of multi-hued graphics.
The graphics were designed to evoke a response from the observers to help
the experimenter investigate the difficulties associated with the inability to
discriminate colors. Twelve of the observers (eleven males and one female)
had been previously classified with dichromatic color vision deficiency, as
established by the Ishihara pseudoisochromatic test and /or the Farnsworth-
Munsell 100 Hue test. The control (color normal) group consisted of two
male and one female observers. The experiment indicated that specialized
color deficient-based palettes are beneficial in selecting color schemes to
aid the dichromatic consumer. Once multimedia designers become aware of
this discrimination process experienced by the color deficient observer, they
can respond with appropriate color combinations to minimize these visual
challenges in the daily flow of electronic information via CRT image display.
