About Color & Design
Color sits at the meeting point of design and code, and getting it right means moving fluently between a swatch you like, the exact hex value behind it, and the accessibility rules a real product has to meet. ToolsHub puts that whole workflow in one tab, so designers and developers can sample, convert, and verify colors without bouncing between a graphics app and a pile of browser tabs.
Start by choosing and translating color. The Color Picker & Converter lets you grab a shade and read it in HEX, RGB, and HSL at once, the Color Converter handles the same job when you already have a value, and the Color Name Finder turns a code into its closest named color. The Image Color Extractor pulls a ready-made palette out of any photo, which is a fast way to build a scheme from a brand image or a piece of inspiration.
For building a system there is the Color Palette Generator and the Color Shades & Tints Generator to expand a single hue into a usable range, plus CSS-ready helpers: the CSS Gradient Generator, CSS Box Shadow Generator, CSS Border Radius Generator, and Glassmorphism Generator hand you copy-paste code. Crucially, the Color Contrast Checker and Color Blindness Simulator test whether your choices stay readable and inclusive before they ship.
Every tool runs entirely in your browser, so nothing you upload or sample is sent to a server, and there is no account to create. Whether you are matching a brand, prototyping a component, or auditing an existing palette for accessibility, you can copy the values straight into your stylesheet and keep moving.
