+ + + + +``` + +Note: `transparent` is not a valid `` value. The popup.js code must handle this: when loading settings, map `"transparent"` to `#ffffff` (or a sensible stand-in) for the color picker; when saving, if the default for that field is `"transparent"`, provide a "Use transparent" checkbox next to the background color pickers. Alternatively, use a text input instead of a color picker for background fields.
