Periodic table legend

Summary

 * I designed this color set for offwiki usage in Jan 2020. Requirements
 * Uses 9-cat + unknonw categoeries, roughly our 2018 classification.
 * Fontcolor is black only (print, no weblinks). Contrast check gives AAA for these! (and wl-blue is devastating...).


 * Rainbow order by design
 * LN and AN have same hue + darkness effect. So 7 hues used.

Color set

 * Note: OM and HAL are used with the same color, to show th 2018 cat class. (2020= OM and HAL different color).

Contrasts





 * }
 * For practical purposed, "DP-2020-rainb" sets HAL = ONONM (same category in 2018)
