dark grey (brightness 15%), magenta (319° brightness 29%), red (2° brightness 47%), green (138° brightness 71%), yellow (55° brightness 94%) and white (brightness 99%). Overlaid with lines from my edge detection software at the same brightness breaks and colours as the filled-in areas. This all over a horizontal gradient at hue 212°.

Shows the brightness layout used by Seurat, and as can happen with such analyses, this highlights aspects that one tends not to identify all that clearly on the original, in this case for example the animals.
