After my epileptic fit or during?:)
I don't understand what you are suggesting by color. That sounds more like a symbol than a model. For example, the open circle denoting a missing point is a notational device or symbol. A model of a missing point would a very tiny gap in the line, but that would be a poor model and wouldn't work at the end of the line, thus the use of symbols instead.
