Hi,
when using the ThemeColor property and you select color none the output in the console log is -500 and not an empty string that I would expect. Therefor I can not do logic with colors in case I do not set something.
Use case for SVG. If no color is selected in SVG it would become black. So I wanted to select color none and in the hook.js file check if the string is empty and if thats the case assign fill-transparent to my svg otherwise fill-brand-300 or what ever is selected.
