Another paint with a color matrix run on its colors, as Skia's color-filtered shader: each color, unpremultiplied, goes through the matrix, is clamped to 0 to 1 and is premultiplied again. WithColorMatrix(ColorMatrix) makes one.

Examples

LinearGradient sky = new(new Vector2(0, 0), new Vector2(0, 100), new RgbaF32(0.2f, 0.4f, 0.9f, 1), new RgbaF32(0.9f, 0.6f, 0.4f, 1));
NoisePaint clouds = NoisePaint.Fractal(0.02f, 0.05f, 4, seed: 3);

// Noise multiplied onto the gradient, then the whole paint turned to sepia.
Paint paint = new BlendPaint(sky, clouds, BlendMode.SoftLight).WithColorMatrix(ColorMatrix.Sepia(0.6f));
using (RasterCanvas<Rgba8> canvas = raster.CreateCanvas())
{
    canvas.DrawPaint(paint);
