Abstract Human performance on colour discrimination in visual display terminals may be affected by illuminant colours, the level of ambient illumination and background colours of the monitor. Few studies have focused on this topic. This study investigated human colour discrimination ability in a simulated control room. Ten subjects were recruited as participants to perform a series of experimental tasks. The independent variables were three illuminant colours (red, blue, and white), two ambient illumination levels (50 lux and 300 lux) and three background colours (black, blue and brown); the three dependent variables were the colour discrimination ability (error scores), completion time and subject preference. The results showed that the illuminant colours and the screen background colours both significantly influenced human color discrimination ability.
