[Geojs-users] Question about LegendWidget

[Jonathan Beezley]

Hi Erik,

The legend predates when we were attempting to normalize how colors are
represented.  It looks like it expects a valid CSS representation of
color.  You can use the method geo.util.convertColorToHex
<https://github.com/OpenGeoscience/geojs/blob/master/src/util/init.js#L305> to
convert anything accepted elsewhere in geojs to a hex string.
