These signatures can help to understand why certain objects appear as they do on black and white or color imagery. These shades of gray are referred to as tone. The darker an object appears, the less light it reflects. Color imagery is often preferred because, as opposed to shades of gray, humans can detect thousands of different colors.

A binary image is a digital image that consists of pixels that can have one of exactly two colors, usually black and white.
This article is also about off-white colors that vary from pure white in hue, and in chroma (also called saturation, or intensity).

A green apple for instance looks green to us at midday, when the main illumination is white sunlight, and also at sunset ...
Here is an example of color channel splitting of a full RGB color image. The column at left shows the isolated color channels in natural colors, while at right there are their grayscale equivalences: Composition of RGB from three grayscale images. The reverse is also possible: to build a full-color image from their separate grayscale channels.
