Tom Patterson's cross-blended hypsometric tints - legend

"Map legend: Lowland colors in the first three elevation scales (from left) depict generalized environments. Above 1,000 meters the colors are identical and rather conventional. The polar scale uses unrelated colors and is shorter because no peaks exceed 5,000 meters in these regions."
From Tom Patterson on cross-blended hypsometric tints
