Themes
strata ships 28 themes. Press T to open the picker — the theme changes as you move, and esc brings the old one back. To keep a theme, set it in your config:
[general]
theme = "tokyo-night"
transparent = false # true uses your terminal's background…and 20 more, plus your own in themes/*.toml.

strata is the default. The terminal theme uses your terminal's own 16 colours.
Custom themes
A theme is 13 colours; every other colour in the UI is derived from them. Create ~/.config/strata/themes/<name>.toml:
# ~/.config/strata/themes/midnight.toml
inherits = "tokyo-night" # start from any theme, then override
bg = "#0f1117"
surface = "#171a23"
overlay = "#2a2f3d"
fg = "#d8dee9"
muted = "#6b7280"
red = "#f87171"
orange = "#fb923c"
yellow = "#facc15"
green = "#4ade80"
cyan = "#22d3ee"
blue = "#60a5fa"
purple = "#c084fc"
accent = "#22d3ee" # borders, titles and the cursorColours are #rrggbb, #rgb or a named ANSI colour such as red. A broken theme file is reported when strata starts and the others still load.
