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. Somewhere along the way I fell hard for design: 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.

Turns out I wasn't the only one. Others showed up, it grew, and now it's a real product. Still wild to me.

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

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 themes 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 themes meet these standards for accessible design.
What is auto-generation?
Auto-generation lets you instantly create high contrast color pairs with one click or by pressing spacebar. It's a Pro feature that guarantees every combination meets WCAG contrast requirements.
Can I export my themes?
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.
