Themes
Greenhouse does not have one look. It has four layouts and ten themes, and you change either from the console without reinstalling anything.
How it works
A layout is structure
Cabinet, List, Blades, Grid. A layout decides where things go — a wall of cover art, a column of rows, a stack of blades — and every screen in the app is drawn through it.
A theme is data
A theme names a layout and supplies the rest: colours, type sizes, corner radius, row height, and optionally its own font and background image. That is all a theme is.
So themes can be downloaded
Because a theme carries no code, new ones install from the repository the way add-ons do, signed and checked. A theme package containing anything executable is refused.
All 10 of them
Nine of them come with the app; the rest are installed from the repository. Each sample below is drawn from that theme's own colour values — background, panel, selection bar and accent — not from a screenshot.
Greenhouse
The standard look, shared with this website: a glass cabinet on a dark desk, drawers down the left, and the library as cover art rather than rows of text.
Greenhouse Dark
The plain dark list the launcher started with. No gloss, no gradient, the shortest path from a name to a game.
Greenhouse Light
The same list on a white page, for a bright room or a television that runs hot.
Glass
Glass panels with a sheen, the way a desktop looked in 2009.
Blades
The 2008 console dashboard, in Greenhouse green.
Three Eras
Three eras at once: a blade stage, pale glass, bright cells.
Linen
Linen behind, bright cells in front, a bar top and bottom.
Catalogue
A printed catalogue: paper, a serif, and wide margins.
Bulletin
Newsprint: ruled rows, square corners, one spot of green.
Phosphor
A green monochrome CRT: one hue, hard edges, no gloss. Installed from the repository rather than shipped, and it carries its own font and its own background image.
Changing it
Press LB on the library wall and pick one. The change is immediate and it applies to every screen in the app; the in-game overlay is rebuilt in the new theme at the same time, so it matches the next time you launch something. Text size and the TV safe-area inset live on the same page, for a television that cuts off the edges or a sofa that is further away than the designer assumed.
