The Tritone effect maps the scene's shadows, midtones, and highlights to three specific colors, allowing for more complex and artistic color grading. Applied Tritone Formula: if (L < 0.5) Result = (1 - 2L) * Shadow + 2L * Midtone else Result = (1 - 2(L - 0.5)) * Midtone + (2(L - 0.5)) * Highlight Where the L is Luminance. issue: https://github.com/thorvg/thorvg/issues/2718
