JUST Normlicht - Color Viewing Light booths
In order to reliably assess the colors of surfaces and materials, natural light is not suitable. Indeed, throughout the day – but also throughout the year – its spectral emission constantly varies, and consequently, the visual rendering. The visual appreciation of color is essential when sorting or inspecting colored products and materials. It is only after making this visual estimate that color measurement takes place and tolerances are determined. This determination of color sensation is not simply important under a single lighting condition – metameric colors that appear identical under a certain lighting suddenly exhibit high contrasts when exposed under other light sources, the estimate resulting visual then being different. In accordance with the standards in force for the visual appreciation of color, the colored samples must appear identical when they are observed under a daylight type D65, but be able to present a certain divergence when they are observed under another light source. – what is called metamerism. Color Viewing Light booths give inspectors the means to detect the presence of metamerism in time.
