Well, this is more for the developer than the "average user". Basically all you need to know is a little color theory. i.e. the color wheel is 360 degrees -- therefore, 180 is a "complementary color", 120 is really two primary colors clockwise (I like these combinations). As for the saturation, that is like the difference between pure (1) or muddy (less than 1) and for brightness between bright (1) and less bright (less than 1).
OK, you're probably wondering what the use is. Well it is the color combinations more than just singular colors. So, say you have a color that your client likes -- i.e. dark blue -- and you want a secondary color that goes nice with it, so you adjust it (for instance) $color->color_adjust($adjust_hue = 120, $adjust_saturation = .3, $adjust_brightness = .2). (I have no idea what that makes, but some kind of light yellow). And there you go, you have your secondary color.
Now, whenever you adjust your original color -- say, the customer changes there mind to greenish-blue -- then the secondary color changes automatically.
Well, I think that's cool!π
