HSL Masking Panel gives you precise control over color selections without the hassle of harsh edges and messy masks. Easily isolate specific ranges of Hue, Saturation, and Lightness, and use smooth falloffs for natural transitions.

Features:

• Hue, Saturation, and Lightness Ranges: Control your selection boundaries using 4-point curves. Drag the points to set your main color range and adjust the side slopes for smooth, natural falloffs.
• Quick Range Adjustments (- / +): Effortlessly shrink (-) or extend (+) your selected color ranges with a single click.
• Color Pickers: Sample colors directly from your image, or use the additive eyedropper (+) to expand your selection.
• Mask Preview & Inversion: Enable "Show Mask" to see your selection in real time, or use "Invert Mask" to target everything outside your chosen range.
• Independent Channels & Resets: Enable or disable Hue, Saturation, or Lightness individually, and reset any channel with one click.
• Direct Mask Creation: Turn your color selection into a ready-to-use layer mask using the "Create Mask" button.
