The intent here is to bring out-of-gamut colors back into gamut, while minimizing changes in the relationships between different colors. We've interpreted this as projecting all colors proportionately towards the neutral point until every color lies w

These parameters are primarily the choice of color space used, the category into which a gamut mapping algorithm belongs and whether the approach is image or medium dependent. A succinct summary is then given of the principal trends in gamut mapping studi

Gamut mapping is the problem of transforming the colours of image or video content so as to fully exploit the colour palette of the display device where the content will be shown, while preserving the artistic intent of the original content's creator.

在 CSS 中， color() 函数和 color-mix() 函数会自动进行 Gamut Mapping。 浏览器会根据目标显示器的色域，自动选择合适的 Gamut Mapping 算法。 虽然我们不能直接控制 Gamut Mapping 的算法，但是可以通过选择合适的颜色空间和调整颜色值，来尽量减少颜色失真。

An alternative to convex hull or alpha shape techniques is a set of approaches that involve the segmentation of color space and then the selection of one color per color space segment to represent the gamut boundary.
