Module theme 

The painted scheme: what color returns on the current frame.

A palette change does not snap: the painted scheme blends from wherever it is toward the new target on the slow effects spring, and a further change retargets from the current paint. Reduced motion paints the target at once.

Functions

advance_component_theme

Advance Material paint and its enabled Component projection before Root rendering. Call from theme/scale events and next-frame callbacks, not from Render. Returns whether the animation needs another frame; the caller owns scheduling and should retain only one pending callback. This function never schedules an animation itself. Base-only callers remain supported.

applyDeprecated

Paint preference resolved against the system appearance. Call at the start of each root render; it schedules frames while a transition runs. Returns whether the paint changed this frame, so an application can mirror the scheme into other toolkits only when needed.

apply_paletteDeprecated

Paint one palette, transitioning from the current paint.

apply_scaleDeprecated

Set the text scale: 14px is 1rem at 100%, and every rem token follows it.

apply_scheme

Apply a complete custom semantic scheme with the same animated transitions.

blend

Linear interpolation between two GPUI colors: Color::blend, the one implementation, applied to GPUI’s color type.

color

The current paint of a role.

init_component_theme

Enable the Component theme bridge after gpui_kit::init, before opening a window or returning its content builder. Initialize from the final startup palette and scale, including capture overrides, so the first Root preparation sees the correct colors and rem size. Returns false when Component is absent. No transition is started for this initial paint. The bridge owns the sans family from Material’s current body type scale, its base size and projected colors. The projection does not own monospace fonts or unrelated geometry; Component mode configurations retain their normal behavior for those fields.

is_dark

Whether the painted scheme is a dark one. Mid-transition this follows whichever palette the paint is closer to.

rgba

Convert a kit color to GPUI’s.

scheme

The current paint as a whole, e.g. to mirror it into another toolkit’s theme.

system_dark

Whether the system currently asks for a dark appearance.
