Watercolor map of agricultural areas looks very urban

[jan-gerard]

Cultivated land (grassland, agriculture, crops) looks very urban (brown) on the watercolor maps. Many areas of the world therefore look very much less green than they actually are.
Would it be possible to add a light-green color area to the maps? Or something else? At least, the world is a lot greener than the average Stamen watercolor map now suggests, if only the cultivated part of the world (I mean, the parts that are neither forest nor full of buildings) would have a different color than that now used for cities.
I can imagine that there are lots of similar requests, to add whatever distinction and its own color, but I think this would be a major improvement, as half the world is green, but now shown as brown.
