Translucency
Translucency (from Latin trans 'through' and lux ' light ') is the partial light permeability of a body.
Wax , human skin , leaves and many other substances are translucent because they partially let light through, but are not transparent (= image or view permeable or transparent) (see volume scatter ) .
The term translucency and the adjective translucent are not used in everyday German , so that the phenomena of partial and “complete” light permeability are usually not differentiated; instead, the foreign word “transparency” (“transparent”) is used for both . Often translucent material is also referred to as "semi-transparent". The Romance languages are more precise because they are directly at the etymological source (e.g. French transparence and translucidité ), while English integrated both foreign words ( English transparency and translucency ).
The reciprocal (mutual) property of translucency is opacity (light impermeability): if a material has a high translucency, it has a low opacity, and vice versa.
Although he did not use the term translucency (and instead wrote “transparency”), the painter and specialist book author Egon von Vietinghoff understood the significance of the phenomenon in the field of painting for the multilayered oil-resin mixing technique - a specifically European cultural achievement - after many decades of Disregard rediscovered. The sum of his systematic research and 35 years of experimentation is collected in his handbook on the technique of painting , in which, among other things - for the first time from the perspective of a creative artist - he defined this fourth property of colors .
