HSL Color Mixer

Fine-tune individual colors with Hue, Saturation, and Luminance sliders.

HSL Color Mixer

The HSL Mixer lets you adjust individual color ranges in your image without affecting other colors. This is the go-to tool for making skies bluer, greens richer, or skin tones warmer.

Color Channels

Fovea provides 8 color channels, each with independent sliders:

  1. Red (0°)
  2. Orange (30°)
  3. Yellow (60°)
  4. Green (120°)
  5. Aqua (180°)
  6. Blue (220°)
  7. Purple (270°)
  8. Magenta (320°)

Sliders

Each channel expands to reveal three sliders:

SliderRangePurpose
H (Hue)±30° or ±180°Shifts the hue of that color range
S (Saturation)±100Increases or decreases saturation
L (Luminance)±100Brightens or darkens that color range

All sliders feature context-aware gradient tracks — the slider backgrounds dynamically show the color shift you’re applying.

Hue Modes

Toggle between two hue modes using the icons at the top-right of the panel:

  • Granular (link icon) — Limits hue shift to ±30°, ideal for subtle corrections (e.g., making orange skin tones slightly warmer).
  • Full Spectrum (arrow icon) — Unlocks the full ±180° range, allowing dramatic color transformations.

Click-to-Expand

Channels are collapsed by default to save space. Click a channel’s header row to expand it and reveal the H/S/L sliders.
