Is it always possible to a darkening effect by calculating a fraction of the whole rgb or does it just work with things like /2 /4..? Does one need to calc the r,g,b:s individually if you want to do .8,.9 etc??
If I for the speed, should make the first line of shadow (the darkest one) be 0.75, the next 0.80, the next 0.9 can it be done without decimal/float?
