I expect the majority of UAs would use their OS's colour picker (or,  
failing that, the de-facto standard on the OS). In the case of OS X,  
this allows entry in many diverse ways: a colour wheel + brightness,  
grey scale, RGB, CMYK, HSB, spectrum, as well as a selection of  
predefined colours. Why do you only need to allow specific colours
