I don't know. That seems like a cool idea though. Then you would see (i.e., not read) all the occurrences of that variable at once. However I don't know how it would work in practice. Perhaps you would just get dizzy. With lots of parameters, perhaps it is better to have them a uniform color, to make a really clear separation what is data and what is metadata, branching, etc. If you were to put it up, I wouldn't recommend random colors, instead you could use the variable *name* (the letters) as function input to be mapped to colors: the first letter - the ASCII position, "normalized" - could be red, the second - same for green - etc. First step if you were to do this would be to examine how colors are setup to begin with. Instead of the static color, you would hook a defun to calculate the color based on the variable name. -- Emanuel Berg, programmer-for-rent.
