Generate accessible color palettes that work for everyone. Simulate protanopia, deuteranopia, and tritanopia preview WCAG contrast, export in multiple formats.
8% of men and 0.5% of women have some form of color blindness. Designing with accessibility in mind isn't optional it's essential. This tool helps you create palettes that are beautiful and inclusive.

The Colorblind-Friendly Palette Generator helps you create accessible color schemes that work for all users, including those with protanopia, deuteranopia, and tritanopia. Design inclusive data visualizations, UI, maps, and accessible text.
8% of men and 0.5% of women worldwide have some form of color vision deficiency (CVD). That's over 300 million people. Designing with accessibility in mind isn't just about compliance it's about creating products that work for everyone.
"Enfin un generateur de palettes qui prend en compte le daltonisme. Je l'utilisé pour tous mes tableaux de bord, les retours utilisateurs sont unanimes."

"La simulation de daltonisme intégrée m'a evite de publier des graphiques illisibles pour 8% de mes lecteurs. Indispensable."

"Je forme des designers e l'accessibilite et je recommande cet outil e tous. La preview UI et les contrastes WCAG sont top."

Standard color palettes often rely on red-green distinctions that are invisible to people with deuteranopia (the most common form, affecting 5% of men). A palette that looks vibrant and distinct to you may be completely indistinguishable to millions of users. Our generator uses LMS-based simulation to ensure every color remains distinguishable across all major types of color vision deficiency.
The tool applies proven color theory adapted for accessibility: it adjusts hue, saturation, and lightness to maximize perceptual distance even after simulation. The result is a palette that works for everyone without sacrificing aesthetics.
Several tools offer colorblind simulation or accessible palette génération. But none combine the full pipeline: génération, simulation, contrast checking, UI preview, and multi-format export all 100% client-side and free. We tested the 6 main alternatives on 12 criteria.
With 4 génération modes, 3-type simulation, WCAG contrast, UI preview, and multi-format export all free and client-side Volade outperforms every alternative tested.

Tested July 2026. "Partiel" = limited or requires paid account.
Most alternatives only offer one piece of the puzzle. Coolors simulates but doesn't optimize. Viz Palette helps data viz but lacks UI preview. ColorBrewer is great for maps but static. Volade brings everything together in one seamless, free, client-side tool.
The free version covers all essential needs for accessible palette génération. V+ unlocks professional export formats and API access for design teams.

The free tier is genuinely useful for most designers and developers. V+ is designed for agencies, design systems teams, and professionals who need Adobe integration and reporting.
Unlike web-based tools that send your colors to servers, everything runs locally. Your designs, your data, your privacy.
Understanding who your palette needs to serve starts with knowing how common each type is:
| Type | Prevalence (men) | Prevalence (women) | Colors affected |
|---|---|---|---|
| Deuteranopia / Deuteranomaly | 5% | 0.4% | Red-Green |
| Protanopia / Protanomaly | 1% | 0.02% | Red-Green |
| Tritanopia / Tritanomaly | 0.03% | 0.03% | Blue-Yellow |
| Achromatopsia | 0.003% | 0.003% | All (grayscale) |
Designing for deuteranopia (the most common type) already covers most cases. Adding protanopia and tritanopia support ensures your palette is truly universal. Our tool lets you optimize for any combination.
Export as Adobe Swatch (.ase), generate PDF accessibility reports, access the REST API, and save unlimited palette history. From 7.99 /month.
Discover V+ PremiumEven the best accessible palette can't solve every accessibility issue. Always combine color with other visual cues: labels, icons, patterns, and tooltips. WCAG 2.2 requires that color is not the only means of conveying information.
