SVG gradient is specified to do the interpolation in sRGB space by default. However officially SVG 1.1 supports interpolation in linear colorspace, but no browser implements it AFAIK. https://www.w3.org/TR/SVG11/painting.html#ColorInterpolationProperty https://www.w3.org/TR/SVG11/painting.html#ColorInterpolation... edit: An other mode of interpolation that is missing even from the spec is using premultiplied alpha. It would be essential to correctly render upscaled transparent raster images, where you don't want to see the "color" of the fully transparent pixels to leak through when it gets interpolated with a neighboring opaque pixel.
