Abstract

The Color vision screener (CVS) test was evaluated for use on visual displays that support the red green blue (sRGB) color space standard. When used on commercial displays in sRGB color mode, the CVS had a sensitivity and specificity (95% confidence intervals) of 0.55 (0.46–0.64) and 1.00 (0.98–1.00). With calibrated displays, all color-deficient observers failed the CVS, but many of these, some with severe loss, were able to pass the test on 10 separate sRGB displays. The CVS test can only achieve close to 100% sensitivity and specificity on fully calibrated displays.
