Some parts of a picture are colored, while others remain as lineart. Could either be from an unfinished picture, or used as part of the image's style.
Monochrome and partially colored are mutually exclusive. For monochrome pictures with just a bit of color, use monochrome and spot color together.
For posts where the only colored part is the background, use greyscale with colored background instead.
