SCALE 8x: Color management for everyone

"On Sunday at SCALE 8x, Inkscape developer Jon Cruz presented a talk entitled "Why Color Management matters to Open Source and to You," putting the need for color management into real-world terms for the average Linux user, outlining current development work on the subject at the application and toolkit levels, and giving example color-managed workflows for print and web production. Color management is sometimes unfairly characterized as a topic of interest only to print shops and video editors, but as Cruz explained at the top of his talk, anyone who shares digital content wants it to look correct, and everyone who uses more than one device knows how tricky that can be.

""If you have eyes and a display, you need color management"

"Color management, broadly speaking, is the automatic transformation of image colors so as to provide a uniformly accurate representation across devices. This includes output-only devices such as televisions and printers, as well as CRT and LCD displays on which editing as well as final output is viewed. The first problem is that every device is capable of generating a different spectrum of colors — different hues, different ranges of white-to-black values, and different degrees of saturation. Collectively, the color capabilities of the device are its gamut, which can be represented by a three-dimensional volume in one of several mathematical color models (or "color spaces")."
