Currently on the pen lifting branch ( #35 ), the colour is changed for each curve drawn, but there is just one colour for pen up movement.
Since in challenges 2&3 we have significant pen up movement, it is desirable to have two sets of colours - one set for pen up movement and one for pen down. For example, we could use blue/purple/pink for pen down and green/yellow/orange for pen up.
