Where does the colour come from?

When the iteration meets the escape condition, we colour that spot on the screen according to the number of times we went around the loop before hitting the escape condition. Like, 10 times = blue, 11 times=green, 12 times=red, or some other kind of colouring scheme. If the iteration doesn't meet the escape condition after, say 101 iterations, then we call a halt and say, "Okay, we must be inside the Set, so we'll never escape. Let's colour this by the Top colour, say bright blue."

FracRove's other colour coding schemes are built by taking the iteration escape value, and end values of other entities, and putting them through various mathematical wringers to get another end value. Here are some examples, with the conventional view first:

It doesn't mean anything, it's just a way of brightening what could otherwise be a dull picture. Incidentally, these fancy schemes always look best with a very low iteration maximum, say 7 to 20.
