While CSS filters give us a solid toolbox of effects like brightness() and saturate(), you can access a much wider variety of color effects using SVG's color matrix capabilities. For example, the feColorMatrix element lets you take the value of any color channel - including the alpha channel - and add or subtract it to/from any other channel. And you can a fixed offset to each channel. Using this, you can create custom greyscales, duotones, and even selective color saturation.
