This is one of the most difficult colors to spell. Its proper spelling is FUCHSIA -- named after Leonhard Fuchs, a botanist -- and no matter how many times I type that it never looks right.
May I suggest correcting the spelling in Cesium.Color and keeping FUSCHIA as an alias as is done with DARKGREY/DARKGRAY?
Thanks Andy! I can’t believe we never noticed that. I’ve filed a GitHub issue here: https://github.com/AnalyticalGraphicsInc/cesium/issues/4973
