Help with Understanding Dynamic Orbits/Phase lanes

I really don't understand how the Dynamic Orbits work, i see colored lines when zoomed out, but i don't understand what they mean.

Is there a guide, or explanation somewhere on how they work? I've searched the forum (all 14 pages at this time) and haven't found an answer. For such a big change/new feature to the game I'm surprised there isn't a good guide with images explaining how it works.

Help me Obi Wan, you're my only hope.
