About Color Changer
Last updated: June 2026
OptiPix Color Changer lets you recolor specific objects or regions of an image by clicking a source color. The click-to-select tool picks any pixel as the source, the tolerance slider controls how similar a pixel must be to be included, and the target color picker sets the replacement. Replacement modes include hue shift (default - preserves luminance for natural-looking recolors like changing a red car to blue), solid replace (flat color), and tint blending. The HSL panel offers per-channel adjustments across 8 color ranges (red, orange, yellow, green, aqua, blue, purple, magenta) for surgical color edits like bluer skies without touching anything else. Color splash desaturates everything except a chosen color for a dramatic single-color-on-black-and-white effect. Full-image transformations include invert, grayscale, sepia, duotone, posterize, and temperature shift. Before/after comparison slider, batch processing, and HEIC input are all supported. Everything runs locally with HTML Canvas pixel operations - your photos never leave your device.
How It Works
The tool reads pixels from the source image via getImageData, finds matching pixels by computing color distance in HSL space within the tolerance, and rewrites their hue/saturation/luminance to the target color. Splash mode does the opposite - desaturates non-matching pixels.
