Monochrome definition (FIAP)

An image is considered to be Monochrome only if it gives the impression of having no color (i.e. contains only shades of grey which can include pure black and pure white) OR it gives the impression of being a greyscale image that has been toned in one color across the entire image. (For example, by Sepia, red, gold, etc.) A greyscale or multi-colored image modified or giving the impression of having been modified by partial toning, multi-toning or by the inclusion of spot coloring does not meet the definition of monochrome and shall be classified as a Color Work.
