DroppyWashTone
What a wash control carries: nothing but the white, or a colour.
enum DroppyWashTone
The two tones Droppy's own Pomodoro and Stay Awake widgets draw their controls in (PomodoroNotchView, CaffeineNotchView). Every control in a widget is neutral except the one action the widget is for, which takes the accent.
Cases
DroppyWashTone.neutral
case neutral
Every other control: white at 15% under the ink at 70% (stop, the stopwatch, Import, Set up).
DroppyWashTone.accent(_:)
case accent(Color)
The one action the widget is for, or a mode that is on: the colour under ink of the same colour (Start Timer, pause and resume). 30% under a disc and 22% under a pill, Pomodoro's two numbers.
