App 2.14.0: accent colour after the MG4 paints; car colour probe

Browse Source 
The accent is selectable in Settings → Display: Dynamic Red (default),
Volcano Orange, Holborn Blue, Racing Green, Camden Grey, Monument
Silver, Arctic White and Black Pearl. White, silver and black cannot be
an accent on the black screen as they are, so they become light greys
and a pearl blue-grey.

The accent palette is now theme attributes (attrs_accent.xml) with one
overlay per paint (accents.xml), applied before the activity inflates;
layouts, colour lists, drawables and the views that draw in code use
them, including the red tints that were hard-coded. A change recreates
the activity on the same page. Android 9 crashes on gradients with
theme colours, so the battery card is built from layers.

Logs → "Look for the car colour" lists the head unit's system
properties that mention colour, paint or car model, to find out whether
the paint colour can be read from the car.

<!-- Accent palettes after the MG4 paint colours, applied over the app theme by MainActivity
(AccentColor.java). Each: accent, text on it, light and deep variants, the tinted card
surface, a muted stroke and the switch track. White, silver and black cannot be an accent on
an OLED-black screen as they are, so they become cool light greys and a pearl blue-grey. -->
