> The main drawback of using these models directly for color picking is that the sRGB gamut has a quite irregular shape in these color spaces. As a result, changing one parameter, such as hue, can easily create a color outside the target gamut, making them quite tedious to use. Yes, and since we use color models in development primarily to model RGB light as displayed by machines, these are less than useful indeed. For anyone looking for a neat color model that is novel and is a bit more intuitive (arguably), look up HCG.
