The colors were pretty easy actually. My mind was already set to make III purple since that’s where Mace Windu has his standoff with Palpatine. Then I thought of the main colors of red, yellow, green and blue. Naturally, blue hed to be for IV, since Luke’s blue lightsaber is the first time we se lightsaber in action. Then I went on with red for V since that’s Vaders color, and finaly green for VI for Luke’s new saber.
For I and II, it was a bit more difficult, because I also wanted red for I, but finally chose orange since that is also a warm color like red, and ended with yellow for II to remind of the whole Geonosis thing.
That’s pretty much it 😃
