In this installation the spectral composition of the yellowish-orange room light changes slowly within a few seconds from combined LED light (Red and Green) to monochromatic LED light (Amber, 590nm). As a result the surface colors appear to be colorful and saturated in one moment and in the other moment monochrome and pale, although the color of the room light seems to remain constant.
However the perceived color palette is limited under the composite yellow-orange light. All surface colors between red and green, including yellow and orange are visible. Blue surface colors can hardly be perceived, since blue and yellow are complementary.
If the light slowly changes to monochromatic light, the surface colors disappear and only light-dark differences of Amber can be perceived.
This light installation impressively demonstrates the dependence of color perception on the spectral composition of the light. Particularly interesting is the constant transition between color perception and monochromatic vision, even if the color of the room light seems to remain unchanged.
