Class StreamDesign.ColorScale

  • @Immutable() 
public final class StreamDesign.ColorScale

    An 11-stop color ramp representing the brand (accent) palette.

    In the Stream design system the brand scale maps to blue by default. Light themes use the natural order (s50 = lightest, s900 = darkest); dark themes invert the mapping so that perceptual intensity stays consistent (s50 is still the faintest tint suitable for backgrounds).

    Re-brand the entire Chat UI from a single color:

    val purple = StreamDesign.ColorScale.from(brandColor = Color(0xFF6200EE))
ChatTheme(colors = StreamDesign.Colors.default(brand = purple))

    For pixel-perfect branding, provide an explicit scale:

    ChatTheme(
    colors = StreamDesign.Colors.default(
        brand = StreamDesign.ColorScale(
            s50 = Color(0xFFF3E8FF),
            // …
            s900 = Color(0xFF3B0764),
        ),
    ),
)
