As I look at the charts that catagorize Greens and Browns, I notice that "fresh" leaves or grass clippings (for example) are listed as "Greens", but when they are "dried" are considered "Browns". How does an organic material go from being high in Nitrogen/Protein to high in Carbon/Carbohydrate just through drying?
Is it the moisture content that determines whether an organic material is classified as a green or brown or is there some chemical change that happens?

Urban area, so no hay, sawdust, wood chipper nearby either. I've been using shredded egg cartons (which look like fairly unprocessed/undyed /easy to degrade cardboard), but we generate only so much of those.
I've just pruned some tree branches from a tree: would letting them dry out in the sun first turn them into "browns" for the sake of keeping my compost healthy? The rest of compost is mostly kitchen scraps.
