![]() ![]() The left circle of each mode is the surface color (color checker), whereas the right circle is the self-luminous color (LC display). ![]() The left image shows the self-luminous color appearance mode, whereas the right image shows the surface color appearance mode. (B) Stimuli from the participants’ views. Two boards were set between the mirrors and the color checker, and the mirrors and the shutter to display the background color in the surface color appearance mode. The lighting was set between the reflectance board and the mirrors for the surface color appearance mode. Participants were placed in a dark room, and observed stimuli reflected by mirrors with their left eye. The light originating from OL490, the LC display, and the shutter was controlled by a laptop that was set outside the experimental room. The self-luminous color (LC display) and surface color (lighten by OL490) were alternately displayed using a shutter set in front of the display and function of OL490. Mirrors were set at right angles to each other. ![]() Our results can be considered to be of great significance not only for color science, but also for the color industry.Įxperimental setup. We experimentally demonstrated that there is no essential problem in cross-media color matching by generating isomeric pairs. However, metameric color matching fails for most participants, indicating that differences in the spectral distributions rather than the different color-generating mechanisms themselves are the reason for the color matching failure between different devices. The results show that isomeric color matching between self-luminous and surface colors can be performed for all participants. Then, we experimentally verified whether such color matching can be performed. In the present study, we created isomeric color-matching pairs between self-luminous and surface colors by modulating the spectral distribution of the light for surface colors. However, the reason for this failure remains unclear. In fact, previous research has reported that metameric color matching fails among diverse media. These are completely different mechanisms, and thus, surface color and self-luminous color cannot be matched even though both have identical tristimulus values. By contrast, self-luminous color results directly from an emitting light, such as a Liquid Crystal (LC) display. Abstract Surface color results from a reflected light bounced off a material, such as a paper. ![]()
