A Site Color Extractor is a digital tool that automatically scans a website and identifies the key colors used in its design. By simply entering a URL, you can instantly generate the website’s color palette, complete with HEX codes, making it easy to analyze competitor branding, find design inspiration, or ensure brand consistency.
Website Color Palette Generator
What is a Site Color Extractor?
A Site Color Extractor, also known as a website color palette generator or CSS color grabber, is a powerful utility for designers, developers, and marketers. Its core function is to analyze the code of any given webpage, parse its Cascading Style Sheets (CSS), and pull out all the color values used to style the page elements. The tool then typically organizes these colors, often identifying the most dominant ones to present a clean, coherent color palette.
Instead of manually inspecting a website’s code with browser developer tools—a process that can be tedious and time-consuming—a Site Color Extractor automates the entire task. By providing a simple interface where a user just enters a URL, the tool does the heavy lifting of fetching and processing the site’s data. The result is a quick, comprehensive overview of the color scheme, with each color’s hexadecimal (HEX) code ready to be copied and used.
These tools are invaluable for a variety of tasks, from competitive analysis (understanding the branding of a rival company) to seeking design inspiration from beautifully crafted websites. They bridge the gap between observing a design and understanding its foundational components, making color replication simple and accurate.

How to Extract Colors from a Website
Using our Site Color Extractor is a fast and straightforward process. Here’s how to get a website’s full color palette in seconds:
- Enter the Website URL: Copy the full URL of the website you want to analyze and paste it into the input field at the top of the tool. Make sure to include
https://. - Start the Extraction: Click the “Extract Colors” button. The tool will begin its analysis process, indicated by a loading animation.
- Get the Palette: After a few moments, the tool will display all the primary colors it found on the site. The results are presented as a grid of color cards.
- Copy Your Desired Color: Each card in the grid shows the color itself and its HEX code. Simply click the “Copy” button on any card to save that specific color code to your clipboard.
How Does a Site Color Extractor Work? The Tech Behind It
Understanding how a Site Color Extractor functions reveals both its power and its limitations. The process typically involves a few key steps, but it’s constrained by a fundamental web security policy known as CORS.
The Ideal Process (Requiring a Server)
A fully-featured Site Color Extractor uses a server-side component (a proxy) to act as a middleman. Here’s how that works:
- User Request: You enter a URL into the tool.
- Server-Side Fetch: The tool sends this URL to its own backend server. This server then makes a request to the target website to download its HTML and CSS files.
- Parsing and Analysis: The server-side script parses the downloaded files. It uses regular expressions or a CSS parser to find all color declarations (like
color: #ff6600;orbackground: rgb(10, 20, 30);). - Aggregation and Display: The script counts the occurrences of each color, identifies the most dominant ones, and sends this cleaned-up palette back to your browser to be displayed.
The Client-Side Challenge: CORS Explained
The tool on this page is built with pure HTML and JavaScript, meaning it runs entirely in your browser without a backend server. This introduces a major security constraint: the Same-Origin Policy, enforced by browsers through CORS (Cross-Origin Resource Sharing). In simple terms, a script from one website (toologi.com) is not allowed to request data from another website (example.com) unless that other website explicitly gives permission.
Because of this, a client-side tool cannot reliably fetch and read the CSS of any random URL you provide. To deliver a functional and self-contained tool that works anywhere (like a WordPress block), we use a simulation. When you click “Extract,” our tool demonstrates its UI and features by processing a pre-defined set of data, showing you exactly how it would present a real palette if the CORS policy allowed it.
Manual Alternative: Using Browser Developer Tools
While a Site Color Extractor is the fastest method, you can also find a website’s colors manually using the developer tools built into modern browsers like Chrome, Firefox, and Edge. This method gives you full control and is a great skill for any web professional to learn.
- Step 1: Open Developer Tools: Navigate to the website you want to inspect. Right-click on any element on the page and select “Inspect” from the context menu, or press
F12(orCmd+Option+Ion Mac). - Step 2: Use the Element Picker: In the developer tools panel, find the element picker tool (it often looks like a square with a cursor arrow). Click it to activate it.
- Step 3: Hover Over Elements: As you move your mouse over different parts of the website, the developer tools will highlight the element’s HTML in the “Elements” tab and its CSS rules in the “Styles” tab.
- Step 4: Find Color Codes: In the “Styles” pane, look for CSS properties like
color,background-color, andborder-color. Next to each color value, you’ll see a small color swatch and the corresponding HEX or RGB code. You can click on the swatch to open a more detailed color picker and see its various code formats.
While effective, this process must be repeated for every different colored element on the page, which is why an automated Site Color Extractor is such a valuable and time-saving tool.
Frequently Asked Questions
This tool runs entirely in your browser for security and portability. Browsers enforce a security feature called CORS (Cross-Origin Resource Sharing) that prevents a script on one domain from reading data from another domain. To bypass this would require a server, which is outside the scope of a self-contained tool. Therefore, this tool simulates the process to demonstrate its UI and capabilities.
Advanced Site Color Extractor tools use algorithms to find the most meaningful colors. They don’t just list every single color. First, they group very similar shades (e.g., #000001 and #000002) into a single color. Then, they might count how many pixels on the screen are covered by each color group. The colors that cover the most area are then presented as the dominant palette.
Yes, it is generally legal. Color combinations themselves cannot be copyrighted. The colors used on a public website are considered public information. However, using a company’s exact color scheme to impersonate them or otherwise infringe on their trademark could have legal consequences. Using extracted colors for inspiration or analysis is perfectly acceptable.
Not always. A Site Color Extractor shows you the colors that are *actually used* in the website’s live code. A company’s official brand guide might specify slightly different colors, or contain colors reserved for print that don’t appear online. For web-related work, the extracted colors are often more practical than the official style guide.
A standard Site Color Extractor works by reading CSS code, so it will not analyze the contents of image files (like JPEGs or PNGs). To get colors from an image, you would need a different type of tool, often called an “Image Color Picker” or “Color Palette from Image Generator.”
Once you have the palette, you can apply it in many ways. Use the main colors to set up your primary, secondary, and accent colors in your own CSS. Use them to create graphics in Canva or Figma that match a brand’s aesthetic. Marketers can use them to create social media posts that are consistent with the company’s website.
Good design often avoids using pure black (#000000) for text. A slightly softer, off-black (like #1a1a1a) is easier on the eyes. Designers also use multiple shades of grey for different elements to create a subtle visual hierarchy: a dark grey for body text, a medium grey for subheadings, and a light grey for borders or disabled states. A good Site Color Extractor will show you this nuanced approach.
Yes, absolutely. This tool is fully responsive and designed to work perfectly on any device, from a large desktop monitor to a smartphone. The layout will adapt to your screen size for a seamless user experience.
