白黒
A completely colorless, black-and-white image. The image is composed exclusively of shades of black, white, and grey. It is very common for [[comic]]s and [[doujinshi]] to be in greyscale.

The image may have small highlights of color (known as [[spot color]]s), but the image as a whole should be predominately greyscale.

Don't use color tags like [[black eyes]] or [[black hair]] when tagging greyscale images. The exception is color background tags, so tagging [[white background]], [[grey background]], or [[black background]] is fine.

h4. Guidelines

* For completely colorless art, use [[greyscale]].
* For a post consisting of a single color that isn't grey, use [[monochrome]], not [[greyscale]].
* For a mostly greyscale post with a small amount of color as a highlight, use [[greyscale]] and [[spot color]].
* For a post using a mix of color and greyscale, use [[partially colored]], not [[greyscale]].
* For a colorless foreground and colorful background, use [[greyscale with colored background]], not [[greyscale]] or [[partially colored]].
* For a post that has solid black shadings, use [[greyscale]] and [[high contrast]].
* For posts with a small variety of colors but more than two actual colors, use [[limited palette]], not [[greyscale]] or [[monochrome]].
