Flo, creator of Huebert

Hi, I'm Flo 👋

the creator of Huebert!

I've been a software engineer for more than a decade, mostly shipping things, breaking things, and fixing them again. Along the way I had to deal with UI design over and over again: apps, logos, little details that either feel right or drive you quietly insane.

That meant I was forever tinkering with colors and themes. After one too many guesswork sessions, I built Huebert for myself: something fast, flexible, and actually pleasant to use.

I hope you have fun using it, and I'd love to hear your feedback anytime.

FAQ

Frequently Asked Questions

Is the high contrast generator free?
You can manually edit colors, lock colors, reorder them, toggle light/dark mode, and export for free. Auto-generation, color harmonies, hue & saturation configuration, the AI assistant, and saving colors are Pro features.
What is WCAG contrast?
WCAG (Web Content Accessibility Guidelines) defines minimum contrast ratios between text and background colors. Our generator ensures your colors meet these standards for accessible design.
What is APCA contrast?
APCA (Accessible Perceptual Contrast Algorithm) is a modern contrast method proposed for WCAG 3. It measures how readable text is against a background based on human perception. Our generator shows APCA values so you can check that your colors meet accessibility standards.
Can I export my colors?
Yes! Export as CSS, SCSS, JavaScript, JSON, CSV, XML, SVG, images, or share via URL.
Can I customize the generation?
With Pro you can adjust color harmonies and hue & saturation ranges to guide the generator. You can also lock one color and regenerate only the other.
Does Huebert have an API?
Yes. Huebert offers a public HTTP API for programmatic access to palette and theme generation, color utilities, image color extraction, and your saved library. API access requires Huebert Pro and an API key. See the API documentation for endpoints and authentication.
