The meaning of Robert Lang's Crease Pattern Lines

[PleatBox]

I have been browsing Robert Lang's site lately, specifically the crease patterns, And I was wondering if what each line in those crease patterns represent? for example the CP for the aedes aegypti. There are red,green, blue, and grey solid lines, and dashed versions of them (except blue,grey, and green). Also, there are dashed lines colored pink and brown. Some solid lines even have different thickness. Now what I know right now are that dashed lines and solid lines are the ones that differentiate what a mountain and a valley fold is, I think. For the colors though, I have no idea. Help will be greatly appreciated!

If I remember right (don't have my copy of ODS on me), he uses different colors to denote hinge creases, axial creases, etc., as well as axial+ creases where they're needed. But I think you only need to worry about the mountains and valleys--at least for the most part.
