Not sure if you understand the significance of the various colour spaces? Can you honestly say that you are clear about the differences between Adobe RGB (1998), sRGB, Apple RGB and Wide-gamut RGB? Well, colour is a complex matter and you could spend the rest of your life studying the science of the subject. In an effort to help, and with the assistance of Bruce Lindbloom, we have introduced a 3-D gamut viewer which displays a variety of commonly-used colour spaces. The viewer even allows you to compare two three-dimensional RGB working spaces by drawing one inside the other. The whole display can then be rotated in any direction, or zoomed in and out, to help you focus on those crucial areas of difference. At last it is possible to visualize clearly how switching, for example from Adobe RGB (1998) to sRGB, imposes significant changes upon your images.
