Certain color hues are more easily distinguished by the human eye than others
the verdict
SUPPORTED
the evidence backs this
confidence 79/100
Empirical studies mapping human color vision and discrimination thresholds confirm that visual sensitivity varies across the color spectrum, making certain color hues more easily distinguished than others.
