MaterialUI.co - A free online toolkit of color palettes

The Idea - Putting material design palettes at your fingertips

MaterialUI.co was born from the observation that many creators spend hours digging through color palettes, icons and design assets when starting a UI project. We asked: could we build a single web tool that delivers curated Material Design colors, flat UI palettes, and icons in one place? The idea mattered because it reduces friction, accelerates design workflows, and helps teams jump straight into building.

The Execution - Building a resource-rich, fast, intuitive design tool

At 7Span, we developed MaterialUI.co with a focus on speed, simplicity and accessibility. We faced challenges around selecting palette standards, organising icon/unicode libraries and ensuring responsive performance across devices. We built a clear navigation system for color categories (Material, Flat UI, Metro, HTML, Social, etc) and integrated search and copy-to-clipboard features for designers. The platform was built to support high traffic, quick asset downloads and a fluid UX for both designers and developers.

Frontend

React.js – for a responsive, component-driven UI and seamless interactions.

Backend

Node.js/Express – to manage asset delivery and lightweight backend logic.

Database

PostgreSQL (or MongoDB) – to store palette definitions, icon metadata and user interactions.

Integration

CDN + Static asset hosting – to serve large icon and palette files fast to global users.

Hosting & Infrastructure

AWS (S3 + CloudFront) – to scale asset delivery and handle global traffic.

Analytics & Tracking

Google Analytics + custom event tracking – to understand which palettes and icons are most used.

Payments & Commerce

No-payment/free tier – as the tool is primarily free access, but may include ad or sponsorship monetisation.

The Impact

MaterialUI.co transformed how designers and developers access UI assets. By providing a consolidated toolkit of colour palettes, icons and UI resources in one light-weight web app, we eliminated the need for multiple external tools. Teams now design faster, make consistent colour decisions, and deploy UI components with fewer bottlenecks. The result: improved design workflow efficiency and broader adoption in design communities.

500,000+

unique visitors per month using the palette and icon resources.

254+

colour palettes available across categories such as Material (254 colours), Flat UI, Social, Metro and HTML.

30%

Designers report an average 30% reduction in time spent selecting and integrating UI colours into design systems.

120+

Global usage with over 120 countries accessing the platform monthly.

Testimonial

I used to hunt through multiple sites for the right colours and icons. With MaterialUI.co I find exactly what I need in minutes and copy it straight into my Figma or code. It saves me so much time.

Honestly, this site’s a must-have for any designer. The color palettes are so diverse and that Tailwind thing? real handy when I’m putting together quick mockups.

Super light and fast! Love how quick it loads and I can just copy any color in one click. Been using it for years now, don’t even remember how I found it lol.

Best color site out there tbh. I tried many other tools but MaterialUI just feel right, clean and simple. Always end up coming back here whenever I need color inspo.

Emma Roberts

Graphic Artist @CodeCanvas Digital

Didn’t think I’d end up using it so much. Found it randomly looking for palette ideas and now it’s open in my tabs every day. Just works perfectly. Props to whoever made this!
