mono Monochrome

Applies an overall monochromatic hue change.

The mono parameter can take a 3- (RGB), 4- (ARGB) 6- (RRGGBB) or 8-digit (AARRGGBB) hexadecimal value. The “A” in a 4- or 8-digit hex value represents the color’s alpha transparency and therefore the intensity of the monochromatic transformation. The higher the intensity, the closer you will get to a duotone effect.
