Subject: [PATCH] fix(ui): hacky fix for updating colors on pure black setting
 change

This is to avoid restarting the app to see the resulting color change,
when changing the pure black setting.

It'll be good to call `finish()` on the settings activity,
to avoid stacking activities every time the setting is changed.
