I don't understand what the y-axis on the graphs mean, and what the second color for each series represents.

Per the small text at the bottom of the poster I would say they are based on shipment volumes -so how much is available. The lighter colour probably indicates variation depending on how good the growing season is

		Yes, this is correct. Realistically, you only care "is it there", and "is it there and good", and those are the two levels. For SF, I'm using shipment volume as a proxy for ripeness, on the assumption that the best produce occurs when you're shipping the most of it. The shaded parts are when the annual history says that it's only good in some years but not others. I decided against a legend because I thought that it was self evident. Maybe not... https://vertumnus.fyi/about/transcript?view=topic%3Aposter-f...

I guess the second color is the margin of error or wiggle room on the prediction.

There's no y axis labeled or marked, the visual is vertically spreading each curve out so it's not all one big color jumble. Not sure what the second color means exactly either.
