The next path is the path of Recursion which is the specific absence of both Evolution and Apparent Causality. Evolution goes up then right, Apparent Causality goes right then up. So Recursion as the specific absence of both of them goes across and up, then across and down. This reflects that it is the underlying cause of Evolution and Apparent Causality.

So, 2 6 4 7 3 5 which is Purple Blue Green Yellow Orange Red.

With Purple standing in for Violet that's the order of colors in the Rainbow.

Things come together at 2 Purple Combination, if they cohere they form a 6 Blue Context. If the Context lasts any length of time it's because there is a 4 Green Commitment. If the Commitment is firm, the things form a 7 Yellow Unity. If communication within the Unity is fast enough you get a 3 Orange Individual which then has 5 Red Choice. This being how a Polyp made up of individual cells that can live on their own, but are more efficient as a group effort, turns into a Polyp where the cells have become specialized and cannot live on their own. That can then evolve into a mobile Worm, which can develop a notochord and become a Fish and then the sky's the limit. 
The entire sequence of the primary rainbow is the clear center at 10 9 8 generates 1 2 6 4 7 3 5 which stabilize at 9 8 10
