If you have some image data stored with reference to one color space, and you want to convert the data to a different color space (e.g. because you are targeting some particular output device), that is a gamut mapping problem. To learn about different trade-offs involved in choice of gamut mapping algorithms, I recommend Ján Morovič’s monograph, https://www.wiley.com/en-us/Color+Gamut+Mapping-p-9780470030... Same story if you want to show your image on a display with a different gamut. Most gamut mapping algorithms used in practice (whether on a display or in software) are actually pretty mediocre in my opinion. It would be possible to do substantially better by writing your own code, at the expense of being a bunch of work. Alas. P.S. The Wikipedia article about color space (and articles about many other color-related topics) is pretty terrible, but I’ve been too lazy to rewrite it. |
