A synthetic demo grid, classed with equal intervals — the point is the palette against real basemap ink, not the data. Switch themes to see how much basemap the palette leaves room for.
Metadata
Provenance
Algae is cmocean's chlorophyll map: a single green family from a pale, almost-white green down to a very dark forest green, with lightness falling steadily. It is the family's answer to the fact that green quantities in the ocean (and on land) are best served by a green ramp that is nevertheless perceptually uniform. MIT-licensed from matplotlib/cmocean.
When to use it
Chlorophyll, vegetation index, canopy cover, crop yield — anything where a green reading is semantically correct and a rainbow would look unserious. It is quiet enough to layer under labels and boundaries without halos in the lower classes. On a basemap that already tints parks and forests green, either desaturate the basemap or switch to a cool ramp; otherwise the reader cannot tell data from landcover.
