Color Vision Improvement of Anomalous Trichromats Based on a Wide-Color-Gamut Display

Abstract

Compared with normal color vision observers (NOs), anomalous trichromats (AT) have anomalous color vision responses owing to differences in cone sensitivity. The wide-color-gamut display provides a promising solution to this problem. Herein, we propose a color discrimination experiment based on a wide-color-gamut display. The observers’ abilities to discern colors in various color directions were tested. The experimental findings were confirmed by simulations based on the shifting of the photopigments spectral absorption. It is concluded that the wide-color-gamut display significantly improves the color perception ability of AT, while proper light source optimization significantly enhances the visualization of AT. The study findings show that this AT-based, color vision model, may open up opportunities for future visual perception and biomedical applications.
