Darkener

A 'darkener' is a substance, object, or process that diminishes the amount of light reaching a surface or an observer, resulting in a reduction of brightness or an increase in shadow. This can involve physical obstruction, chemical reactions, or alterations to the refractive properties of a material. It can be a literal substance like ink or dye, a metaphorical force, or a technique employed to create a desired aesthetic effect such as shading. It’s often used in art, photography, and various industrial applications where precise control over light and shadow is crucial.
