Tips

  • Duotone maps pixel luminance between your dark and light colors.
  • Use light color for highlights and dark color for shadows, then fine-tune.
  • Contrast and brightness shape depth, while saturation adjusts intensity.
  • Blend modes help quickly create poster, cover, and brand visual styles.
