Colour scheme

One of the two palettes (24 passages, no note) of a theme, light (18 passages, no note) or dark (26 passages, no note), in force on a page of the site. The dark palette is a second palette, measured on its own, never an inversion of the light (3 passages, no note) one: its contrasts are checked separately, and it casts (3 passages, no note) no shadow. A page follows the system preference (8 passages, no note) until the reader (note: Reader) presses (4 passages, no note) the switch of the bar (28 passages, no note), which displays the other scheme (19 passages, no note) and remembers (3 passages, no note) the choice in the browser (31 passages, no note); the switch draws (8 passages, no note) the glyph (10 passages, no note) of the scheme it switches to and is pressed (3 passages, no note) while the dark one is displayed.
