ColorSpace

@memory_only
struct ColorSpace

The space colors are mixed in: where a blend or a gradient interpolation does its arithmetic.

SRGB, the default, mixes the stored 8-bit channel values directly, as browsers, Cairo and most raster libraries do; LINEAR converts each channel through the sRGB transfer function to linear light first and back afterward, so that a 50% blend of black and white is the gray that reflects half the light (sRGB 188) rather than the one halfway up the byte scale (128), and a red-to-green gradient does not sag through a dark middle. Canvas.set_color_space and GradientStops.set_color_space choose it; see each for what it covers.
