Coolors' free tier caps exports and gates its palette-from-image and extended-export tools behind a $5.99/month Pro plan. Paletteforge does the generating, locking, contrast-checking and exporting locally — CSS variables, Tailwind config, ASE swatches, PNG — for $15 once.

• Generate & shuffle palettes — Spacebar-driven random palette generation, five colors at a time.

• Lock colors while regenerating — Keep the ones you like, reroll the rest until the palette clicks.

• WCAG contrast checker — Instant AA/AAA pass-fail for any foreground/background pairing in your palette.

• Export to CSS, Tailwind, ASE, PNG — Drop straight into a codebase or design tool — no manual re-typing of hex codes.

• Saved brand kits — Name and keep multiple palettes per project or client.

• Extract palette from an image — Upload a logo or photo and pull its dominant colors automatically.

• Shade & tint ramps — Generate a full 50–900 ramp from any base color for design systems.

• Fully offline — No image or color data is ever uploaded — all generation and extraction runs locally.

Runs as a Windows desktop app.
