What is the term for a map of color points?

The correct answer refers to a map of color points as a raster. In digital imaging, a raster graphic is composed of a grid of pixels or points of color, which define the image. Each pixel in a raster image holds specific color information, forming a complete picture when viewed collectively. This is particularly relevant in contexts such as digital photography or detailed illustrations where images are represented in a pixelated format.

Raster images are distinguished by their resolution, which is determined by the number of pixels in the image. Higher resolutions yield more detail, as they contain more color points concentrated in a given area. This is why rasters are essential when dealing with complex images where varying colors and shading are necessary to create an accurate representation.

Other terms, while related to color and design, do not specifically describe a map of color points in the same manner. A vector, for example, refers to graphics created using mathematical equations rather than individual color points. A palette typically refers to the selection of colors available for use in a design but does not embody the concept of a map of those colors. A gradient represents a gradual transition between colors but does not imply a grid or map structure. Thus, raster is the most appropriate label for a map of color points.
