LIBRARY SUMMARY

---

The palettes in this library are ported from ColorBrewer:

https://en.wikipedia.org/wiki/ColorBrewer

The palettes can be sequential, divergent, or qualitative. The name of each

palette ends with its color count (= how many colors the palette comprises).

Some palette names include color abbreviations such as Bu for blue, Pu for

purple, Yl for yellow, etc.

The list of available palettes follows. For brevity, palettes with the same

base name but with different color counts (e.g., AccentQual3, AccentQual4, ...

AccentQual8) are listed as a single name followed by a numeric range (e.g.,

"AccentQual 3-8").
