For example if I have a color hsl(210,50%,40%) and want one at one third of the level can I use hsl(210,50%,13.3%)? Is it actually going to be any different to hsl(210,50%,13%)? > > Firefox and Opera seem to handle it fine, but I'm not sure if they're just rounding things internally or something. > > Rob > The Color module mentions that the first value for hsl() is a number, and the two following values are percentages. According to the Syntax module[1], percentages get parsed as: [0-9]+|[0-9]*"."[0-9]+ % So syntactical speaking: yes, they are allowed. I wouldn't know whether the displayed color differs based on the fraction for any browser. Can't you compare the displayed colors of "hsl(210,50%,40.999%)" with "hsl(210,50%,40.001%)"?
