It is a three-dimensional representation variant of the rgb color model, and is also considered an hsv optimized for more intuitive use by designers. It is the acronym for the English Hue ( "tint" , Saturation ( "saturation" ), Lightness ( "luminosity") which presents the hue as a color gradient also at 360 0176; , and saturation between 0 and 100%, both as the HSV. The difference is that lightness has the pure color at 50%, while the maximum brightness up to white is 100% and the minimum up to black at 0%. This is why it is easier to understand, since its three-dimensional graph would be two cones joined by the bases, which would be the disc with colors, and towards one vertex the black component and towards the other the white component.
