Yehuda's reply doesn't exactly accomplish what I wanted, since I really intedned that there will be known, predefined sequence of colors - with the last one being white (to erase the segment). You should also note that I didn't wnat the color of lines to change with each new line - nut only when the line is traveresed. This is the curcial point!
