Using an integer then percentages of that integer to describe HSL is very  
intuitive from an author/designer standpoint. It's RGB that's not - and  
yes, confusion because in RGB notation it has to be integer or percentage.  
That's the only stumbling block in changing author behavior when it comes  
to HSL - we work very hard to ensure they understand that in RGB it must  
be one OR the other, in HSL it must be the integer of the hue  
corresponding to the color wheel, and the percentage of saturation and  
light of that Hue. It's really quite sensible as it is, making it more  
complex would cause slow-to-adopt problems, not to mention a lot of  
potential errors.
