You seem to be plotting each segment with a different plot call. One way to plot each constellation is to combine the x-coordinates of the constellation in one vector, the corresponding y-coordinates in another vector, and plot them against each other. (You may have to ‘retrace your steps’ in some segments.) They would then all have the same colors.
An alternative is to specify the colors in each plot call for a specific constellation. This might be the easiest way to modify your current code.
I’m not listing this as an Answer because I’m guessing what you’re doing.
