Change a palette without losing track of what changed. Palette Revisions compares two saved palettes, shows perceptual color differences and catches color-pair contrast regressions before you hand off the next version. HOW IT WORKS 1. Open Library → Palette Revisions and choose Before and After palettes. 2. Use palettes with 2–24 colors and the same count. Confirm that colors in matching positions represent the same design roles. 3. Choose a contrast threshold of 3:1, 4.5:1 or 7:1 and compare. Inspect every color change and every pair that falls below the selected threshold. 4. Share the frozen comparison report or export the revised CSS. Changing selections or thresholds clears the previous report. Keep working with saved palettes, color exploration and on-device design utilities. The revision workflow turns those palettes into a reviewable handoff. WHAT TO KNOW Colors are matched by position, not inferred by name or appearance. Pairwise contrast does not certify an entire interface as accessible: text size, weight, state and actual foreground/background use still matter. Existing palettes are not modified. Built for iPhone and iPad. No account required for this workflow.
