Previous value: -"Colour — one of: DEFAULT, LAVENDER, RED, ORANGE, YELLOW, GREEN, DARK_GREEN, LIGHT_BLUE, BLUE, PURPLE, PINK, GRAY, BEIGE. Omit to leave the colour unchanged. `DEFAULT` sets that specific colour; it does not clear/reset the colour — there is currently no way to remove a colour once set. Tabs follow a scheme of one or two colours (an ordinary colour on every tab, plus an accent for the main page and groups where there is one, both taken from the project's tile colours); change one tab at a time, each finishing before the next.

Omit to leave the colour unchanged. `DEFAULT` sets that specific colour; it does not clear/reset the colour — there is currently no way to remove a colour once set. Which colour: first read the project's structure. A page or group listed with `colour <NAME>` has a coloured tab; one listed with only its type (such as `GENERAL`) has no colour. 1) If the tabs are coloured, they are the scheme: a new tab takes the colour of its role in it — an ordinary page the ordinary pages' colour, a group the main page's colour. 2) If no tab has a colour, or the project is new, the colours come from the project's tile colours: the first tile colour gives the ordinary colour, the second the accent; with no coloured tiles, from the topic pair. The ordinary colour goes on every tab; the accent only where the project has a main page — on that page and on every page group. Change one tab at a time, each finishing before the next.
