Key Features
Convert Color Formats
Change color formats between HEX, RGB, RGBA, HSL, HSLA, CMYK, HSV, and CSS color names instantly. Different apps and website platforms use different ways to define colors. This tool takes your color input and immediately translates it into all popular styles. All calculations are done instantly as you type, meaning you never have to wait. This helps designers and developers translate their designs into the exact format they need for their code, making styling components quick, easy, and completely error-free.
Readability & Contrast Check
Make sure your text color is easy to read against your background color. The built-in contrast checker calculates the brightness difference between your text color and background color. It immediately shows simple pass or fail badges for normal text and large text formats. This helps you create designs that everyone can read, including users with visual impairments, ensuring that your website remains readable on custom background settings without extra effort.
Create Color Palettes
Create matching color schemes from any starting color in seconds. The tool automatically generates beautiful combinations like complementary colors, analogous scales, and triadic schemes. You do not need to be a color expert to build balanced interfaces. The generator creates these combinations instantly, helping you expand your color schemes and build professional, cohesive designs that make your websites and applications look visually appealing.
Create Tailwind Shades
Build complete scales of matching light and dark shades instantly. The shade tool calculates color variations from the lightest tint (50) to the darkest shade (950) based on your input color. This gives you a complete range of matching colors to use for backgrounds, borders, hover states, and text. You can copy the generated configuration block directly into your project settings, making design system setup simple and fast.
Export Code Styles
Copy your colors as ready-to-use code styles with one click. Convert your selected colors into CSS variable definitions, Sass variables, or Tailwind configuration code blocks. This saves you from copying and writing variables by hand. It makes it easy to integrate your design settings into your stylesheets, reducing layout errors and keeping your codebase clean, organized, and standardized.
Visual Color Picker
Choose and adjust colors visually using the interactive color board. You can drag the indicators to adjust values like hue, saturation, lightness, and opacity, and watch the converted codes and contrast scores update in real time. This helps you fine-tune your shades visually until they look perfect, combining visual design with real-time feedback and accessibility checking.
Secure & Offline
Your color data and designs remain entirely private. All coordinate conversions, contrast checks, and palette generations happen inside your web browser on your own device. No data is sent to external databases or tracking servers. This ensures you can work with confidential brand assets, proprietary color guides, or sensitive design systems with complete security and peace of mind.
Fast Clipboard & History
Work efficiently with color values. Copy HEX strings, RGB structures, and styling variables with one click, and check color logs to restore previous selections. The history manager records color coordinates, allowing you to restore parameters and review previous color selections easily, optimizing editing tasks.
Usage Examples
HEX: #3b82f6
RGB: rgb(59, 130, 246) HSL: hsl(217, 91%, 60%) CMYK: cmyk(76%, 47%, 0%, 4%)
Common Use Cases
Design System Tokens
Create a consistent color scale for your software projects. Paste your main brand color into the tool to generate CSS variables and Tailwind shade palettes. This helps you set up uniform variables across all components of your website. By using these generated coordinates, you make sure your colors look identical across buttons, menus, and text headers, preventing style mismatches and keeping your user interface professional and cohesive.
Verifying Contrast Ratios
Ensure your website is accessible and easy to read. Check color contrast scores before finalizing your design choices to verify that dark text on light backgrounds (or light text on dark backgrounds) meets readability standards. The checker outputs simple results, helping you adjust your shades to build compliant pages that are readable for all visitors, avoiding layout accessibility errors.
Developing Custom Color Themes
Generate beautiful color palettes for new website themes. Paste a base color to generate complementary, triadic, or matching color groups. This makes developing themes fast and simple. You can easily choose secondary colors, border highlights, and text links that match your main color, allowing you to build clean, balanced visual patterns without guessing.
How It Works

Run Color Space Mapping
The converter parses your input and immediately calculates matching codes across HEX, RGB, HSL, CMYK, and HSV formats. These values update in real time as you adjust the color, making it easy to grab the code you need.
Calculate Contrast Ratios
The contrast engine compares your text and background inputs to determine readability scores based on official web standards. It displays visual ratings to help you quickly verify if your text overlays are easy to read.
Output and Export
Copy the code formats to your clipboard with one click, or export the Tailwind palette configurations directly. All computations run inside your local browser tab, ensuring fast speeds and total privacy for your design tokens.
Frequently Asked Questions
The converter supports HEX, RGB, RGBA, HSL, HSLA, CMYK, HSV, and standard CSS color names. It converts values between these formats instantly in your browser. If you type a value that is slightly off, the validator will highlight the error and help you fix it. It handles modern CSS color styles, making it simple to translate color codes across design files, stylesheets, and native applications.
The contrast checker compares the relative brightness of your text color and background color using standard algorithms. It calculates a score from 1:1 (no contrast) to 21:1 (black and white). Guidelines require at least a 4.5:1 ratio for normal text and 3:1 for large text to pass. The tool checks these ratios instantly to help you build accessible pages.
The shade generator takes your base input color and scales its brightness and saturation. It automatically calculates nine matching shades from 50 (lightest tint) to 950 (darkest shade). This ensures that the generated colors match your main shade perfectly, giving you a balanced scale for backgrounds, hover styles, and text elements in your Tailwind configuration files.
No. All color conversions, contrast checks, and palette builds happen locally on your computer inside your browser tab. We do not track, log, or save your color choices. This means you can work with private company branding guides, unreleased client designs, and proprietary color schemes with complete privacy and safety.
You can export colors directly from the panels. Click the copy buttons next to the CSS variables or Sass definitions to copy them to your clipboard. You can also download the custom scales as configuration blocks. This makes it easy to paste the variables directly into your stylesheets, keeping your code clean and organized without typing hex values manually.
When people visit your website, they should be able to read the text clearly. If there is not enough contrast between the text color and background color, some users will have difficulty reading. This is particularly true for people with visual impairments or when reading on mobile devices in bright sunlight. Ensuring high contrast makes your site easier to navigate and more professional.
RGB defines colors by mixing red, green, and blue light. HSL defines colors using hue (the color type on a wheel), saturation (how rich or gray the color is), and lightness (how light or dark the color is). Developers often prefer HSL because it is much easier for humans to understand and adjust manually compared to RGB.
Yes, CSS variables allow you to store color codes in a single central place in your stylesheet. You can then reuse these variables across your site. If you decide to change your brand color later, you only need to update the value in one place, and your entire site will update automatically, saving you time.
Complementary colors sit opposite each other on the color wheel. Using them helps you create high-contrast highlights, which are perfect for call-to-action buttons, warning alerts, or active navigation tabs. They draw the user's attention to important parts of the page, improving user navigation and engagement.
CMYK (Cyan, Magenta, Yellow, and Key/Black) is the color model used for physical ink printing. While screens use RGB/HSL to display light, printers mix CMYK inks to reflect light off paper. Converting web colors to CMYK helps designers ensure their branding matches when printed on physical materials like business cards or brochures.
