Color Adjuster — Complete Guide

1What is Color Adjuster?

Full HSL color control in one tool.

Color Adjuster is part of the Pixly suite of professional image tools. It runs entirely in your browser with no software to install, requires no design experience, and delivers results in seconds — whether you are processing one image or an entire batch. Every operation is applied on the full-quality decoded image, so the output preserves the fidelity of your original file.

2How does Color Adjuster work?

The color engine applies three operations in a single pass: hue rotation (shifting every color around the color wheel by the chosen degrees), saturation scaling (multiplying each pixel's chroma while keeping luminance fixed), and the brightness/contrast controls from the individual tools. Running them together means the image is decoded and re-encoded once — no stacked generational quality loss.

Hue rotation uses a proper YIQ/HSV hybrid transform so skin tones stay natural at small angles, and saturation is applied in a perceptual space that avoids the neon look of naive RGB multiplication.
