ok i try to reply myself 
i think the easiest way to match a color to a color range is to use a specific HUE value (like "0" for red) and a saturation value (like "150" for light-red). next you have to define a threshold value like 25 (it is to define the range) for saturation and 5 or so for the hue level..
the rest is a simple contruct of "if" statements.
hope this will help.
