selectionPalette option

[marcandre]

In the list of options, there's selectionPalette: [string].

1. There is no other documentation.

2. It appears to be ignored if there is a localStorageKey option

3. In either case, spectrum('option', 'selectionPalette', ['00ff00']) will not update live the selection palette.

1. There is now some documentation at https://bgrins.github.io/spectrum/#options-selectionPalette
2. I've added a note about this in the docs
3. Yes, it's sort of a weird option. I wonder if it should just be removed altogether, since you can specify multiple palettes anyway. The primary use case here is for localStorageKey
