It isn't that difficult: HSV/HSL splits the color information into three channels: Hue, saturation and lightness/value. This way you can easly change the saturation, hue or lightness without influencing the other two channels, contrary to RGB. Many of the modules in the color section provide such operations. http://en.wikipedia.org/wiki/HSL_and_HSV Lab is another color space which splits the information into a lightness channel and two color channels, one for the blue-yellow part and the other for the green-magenta part. For the image editing part, thinking of colors in a HSV/HSL way can often be helpful, i mentioned Lab because it is used internally in darktable, some modules like the tone curve work in this color space.
