Start your rebrand here

Rebranding isn't picking new colors from a mood board. It's replacing one system with another. If you don't treat it as a system, every page, component, and template becomes a manual update.

You've seen it happen. The homepage gets the new blue. Product pages still have the old blue. The footer uses a third blue that nobody can explain. Six months later, someone finds a fourth blue in the email templates.

Systems prevent this. Paletter builds systems.

Paletter's diff tool shows exactly what changed. Delta-E scores quantify the perceptual distance between old and new values. Side-by-side swatches make the difference visible.

Perception labels translate the math into language stakeholders understand: "barely noticeable," "clearly different," "very different." No more squinting at two hexes wondering if anyone will notice.

Present the diff to your team. Get sign-off on the system, not individual colors. Ship with confidence.

Because your old and new palettes use the same role names — background, ink, accent, support, neutral — swapping the token file updates everything. Components don't change. Only values do.

Your button references --color-accent. Your heading references --color-ink. Your card references --color-bg. None of those change. The hex values behind them do.

One file swap. Full rebrand. No broken pages, no orphaned colors, no "we missed the checkout flow."
