I don't know of a way to do exactly what you are after without having a custom character sheet with a roll template built to respond to that range of rolls. However, if you are flexible on the color, there is another way to go about this with the normal dice roller. Anything that registers as a critical success is green. Anything that registers as a critical failure is red. Anything that registers as both will be blue. I don't know if high or low is better in your setting, but the following will show a 1-39 as green, 40-60 as blue, and 61+ as red: [[1D100cf>40cs<60]]
