Color Inversion using various methods including sRGB, linear RGB, Lab, luminance, and hue-preserving techniques. Adjust severity and explore different inversion effects.

Notes
Lab/perceptual inversion is more uniform perceptually and useful for research. Linear inversion preserves energy relationships. Hue-preserve keeps chromatic identity while flipping brightness. ΔE helps quantify perceptual change. Not a clinical diagnostic.

Image simulation

Modes: sRGB inverts after companding; linear inverts in linear-light; Lab inverts L/a/b perceptually; hue-preserve flips lightness while keeping hue; luminance inverts grayscale luminance. Severity blends between original and inverted. Not a clinical diagnostic.

Compare normal, Condition A and Condition B across multiple severities. If an image is loaded it will be processed into the grid, otherwise color swatches are shown.
