Color Picker with "no color" option? I want let the editor to choose an optional color via the color picker, but this didn't have the option 'no color' (or transparent).

Is there a solution to this? I use it a lot and have always to add a boolean switch so the editor can switch it on and off, but that's not the best way to do this.
At the moment there is no better solution for this. You could write a plugin that defines a new fieldtype.
