Fifteen Ways to Depict Elevation on Mars

How do you depict elevation on a map of Mars? Earlier this year, Daniel Huffman posted a roundup of hypsometric tints for Mars.

I have a peculiar hobby of collecting Martian hypsometric tinting schemes: those sets of colors that cartographers use to depict elevations on the Red Planet. It’s a fascinating cartographic frontier. While the classic (and somewhat flawed) way of showing Earth’s elevations is to use a color scheme that starts with green lowlands, and then proceeds through some combination of brown/yellow/orange/red until it reaches white in the highest areas, there’s no standard yet for Mars. Maybe centuries from now, one of the schemes below will become that standard.

Huffman looks at fifteen schemes in total in the post, and in this video on YouTube:
