Why the Right Tools Make Color Work Easier
Even experienced designers benefit from good tooling. Color decisions are complex — you're balancing aesthetics, accessibility, brand consistency, and technical constraints all at once. The good news: there's a robust ecosystem of free tools that can help you generate palettes, check contrast ratios, explore gradients, and much more. Here are the ones worth bookmarking.
Palette Generation Tools
Coolors (coolors.co)
One of the most popular free palette generators available. Hit the spacebar to generate a new five-color palette instantly, or lock individual swatches to explore variations around a color you love. Features include palette export, color blindness simulation, gradient generation, and a massive library of community-created palettes. The interface is fast and intuitive — great for rapid ideation.
Adobe Color (color.adobe.com)
Adobe's free web-based tool lets you explore color harmony rules (complementary, triadic, analogous, etc.) on an interactive color wheel. You can also extract palettes from uploaded images and check for accessibility compliance. Adobe Color integrates directly with Creative Cloud apps if you use them, making it particularly powerful for Adobe users.
Paletton (paletton.com)
A more technical tool that shows color relationships with precision. Paletton is excellent for understanding how to build multi-color schemes systematically — particularly useful for web developers who want to understand the theory behind the palette, not just the output.
Accessibility & Contrast Checkers
WebAIM Contrast Checker (webaim.org/resources/contrastchecker)
An essential tool for anyone building for the web. Enter any two hex codes and instantly see whether they meet WCAG 2.1 accessibility standards (AA and AAA levels) for normal text, large text, and UI components. Non-negotiable for professional digital design work.
Who Can Use (whocanuse.com)
A more nuanced accessibility tool — it shows exactly how many people with different types of color blindness or visual impairment would struggle to read a given color combination. It contextualizes accessibility as a human issue, not just a compliance checkbox.
Color Exploration & Inspiration
ColorHunt (colorhunt.co)
A curated, community-driven gallery of four-color palettes. Great for when you want a fully prebuilt palette to start from. Browse by trending, popular, seasonal tags (pastel, neon, dark, vintage), and save favorites. The palettes are all hex-code ready to copy.
Khroma (khroma.co)
AI-powered color discovery — you train it by choosing 50 colors you like, and it learns your taste to generate personalized palettes, typography pairings, and gradients. It's a different approach from rule-based tools and often surfaces unexpected combinations that still feel right.
Gradient Tools
CSS Gradient (cssgradient.io)
A visual editor for CSS gradients — no code knowledge required. Choose your colors, adjust stops, and copy the ready-to-use CSS. Perfect for web designers adding depth to backgrounds, buttons, and hero sections.
UI Gradients (uigradients.com)
A curated library of beautiful two-color gradients, each with a name and copyable CSS. Browse by feel — from soft pastels to bold neon combinations. A great starting point when you want something with energy.
