Hue shifts colors around the color wheel without changing their intensity or brightness. Moving the slider adjusts all colors by the same amount - reds become oranges, blues become purples, etc. This is perfect for correcting color casts or creating creative color transformations. A full 180° shift turns colors into their complements.

Saturation controls color intensity from completely gray (0%) to maximally vivid (100%+). Decreasing saturation creates muted, pastel, or black-and-white effects. Increasing saturation makes colors more vibrant and punchy, ideal for making images pop on social media.

Lightness adjusts overall brightness while preserving color relationships. Unlike simple brightness adjustment, HSL lightness maintains color saturation better. Increase for bright, airy effects or decrease for dark, moody atmospheres. Works independently of hue and saturation.
