How the Sepia Algorithm Works

The sepia effect uses a standard color matrix transformation applied to every pixel in your image. Each pixel's RGB values are recalculated using these formulas:

  • Red = (R × 0.393) + (G × 0.769) + (B × 0.189)
  • Green = (R × 0.349) + (G × 0.686) + (B × 0.168)
  • Blue = (R × 0.272) + (G × 0.534) + (B × 0.131)

The intensity slider blends between the original and sepia colors, giving you full control over the warmth of the effect.
