Enum ThemeTextColor 

pub enum ThemeTextColor {
    OnSurface,
    OnPrimary,
    OnSurfaceVariant,
    OnPrimaryContainer,
    Error,
}

Which themed color role a text’s glyphs default to when no explicit .color()/.style() was set and a theme is active.

A plain text defaults to ThemeTextColor::OnSurface (body text on the app surface); a crate::Button’s label is built with ThemeTextColor::OnPrimary so it reads correctly against the primary-filled button. The role is only consulted when the color was not set explicitly — an app-supplied .color() always wins (precedence: explicit > theme > fallback). With no theme threaded in, the style’s own color (black by default) is the unthemed fallback.

Part of the widget-authoring toolkit — re-exported as crate::authoring::ThemeTextColor, which is the path a design system outside this crate names it by.

Variants

OnSurface

colors.on_surface — the default for standalone/body text.

OnPrimary

colors.on_primary — a label painted over a primary-filled surface (used by crate::Button).

OnSurfaceVariant

colors.on_surface_variant — a de-emphasized label/caption on the app surface (a navigation bar’s unselected item labels, an app bar’s trailing action slots).

OnPrimaryContainer

colors.on_primary_container — a label painted over a primary_container-filled surface (an extended FAB’s visible label).

Error

colors.error — a label reading as a destructive/error action (used by crate::Button’s ButtonStyle::Danger).
