#TonalColorsOutput

Result of CK.computeTonalColors. Two tonal-adjusted Color Float32Arrays ready to feed into Canvas.drawShadow.

const tones = CK.computeTonalColors({
  ambient: CK.Color(0, 0, 0, 1),
  spot:    CK.Color(0, 0, 0, 1),
});
// tones.ambient and tones.spot are Float32Array (4-component RGBA in 0..1).

Skia adjusts the input colors so that — given the elevation (zPlane) and lightRadius you'll pass into drawShadow — the resulting soft-shadow falloff matches a perceptual model. Don't try to compute tonal colors by hand; the formula changes between Skia versions.
