Assessing colour differences of lighting stimuli using a visual display

摘要: A large scale experiment was carried out to accumulate colour difference discrimination data for lighting stimuli which were simulated on a display. Twenty six centres selected and twenty one pairs of chromaticity prepared surrounding each centre. Each pair assessed using ratio method against grey black background by group 20 normal vision observers. Both white coloured used; corresponding specifications the solid state products part MacAdam respectively. The latter defined fundamental research visual sensitivities known as just noticeable (JND). The results used test spaces diagrams well evaluate predictions various formulae appearance models. It found that u'v' diagram can represent more uniformly. Moreover, CIELUV formula performed better in predicting differences stimuli; especially when background. than CIEDE2000 CAM02-UCS formulae, derived based surface colours, even though it has been shown previous studies these perform simulating colours These points also support experimental arrangement could potentially be simulate light sources (luminaires) order them stimuli. Furthermore, obtained mostly predicted models those lightning
