multiple monochrome
An image which is composed of multiple monochrome subsections, each using a different color.
A common example would be an image in which multiple characters are each drawn using only one color thematically appropriate to them.
Avoid applying this tag unless each character or distinct object in question could, standing alone, be tagged monochrome. However, this tag can apply to part of an image if the tag holds true for that part (e.g. the background of Danbooru post #580199).
If the each subsection is heavily themed on a single color without being monochrome, it's color coordination, such as Danbooru post #6313320.
It's sometimes arranged in a column lineup format.
For spots of differing color on the same monochrome character, see spot color. For colors that blend across an area, see gradient.
