When do you actually need this?

Accessibility contrast testing

Designers invert UI screenshots to instantly spot low-contrast text and elements — simulates certain vision conditions without extra software.

Negative film scanning

Digitised film negatives need a full invert to become positives. Upload, hit invert, download — no Photoshop needed.

Selective channel swap

Inverting only the Red channel turns a warm photo cool. Inverting only Blue creates a vintage warm shift. Powerful for quick colour grading experiments.

Brightness-only invert

Flips dark/light without touching hue — useful for checking if a colour palette works on both dark and light backgrounds simultaneously.
