==== User story
As a reader in low-light and low-power, I want the lowest lighting possible for reading on Android.
//Per user feedback from // <https://github.com/wikimedia/apps-android-wikipedia/commit/05b321f926d9e7f8d905672362f43f9981af0ad4#commitcomment-23632057>
=== Proposed
Create a "Black" color theme with black #000000 used as the predominant background color under text in the app.
**Design details:**
This could be achieved with minimal additions to the color schema defined in T172984:
