# Palette Generator MCP for AI Agents AI Agent Connect > Palette Generator MCP helps you build professional color schemes for web and UI design. It uses the OKLCH color space to ensure colors look balanced to the human eye, providing perceptual uniformity across your entire palette. It also checks against WCAG accessibility standards to guarantee that your text and buttons remain readable for everyone. It handles the math of color theory so you can focus on the design. ## Overview - **Category:** design - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_VzTSLwHAOqHEe6Kfgd2s4JSQKeyBcUdJyUJYC0eN/ai-agent-connect - **Tags:** color-theory, oklch, accessibility, web-design, ui-ux ## Description The Palette Generator MCP lets your AI agent do the heavy lifting of color science. Instead of just picking colors that look okay, you get palettes built on the OKLCH color space, which ensures that different hues actually look balanced to the human eye. It handles the math for you, whether you're trying to find a perfect complementary scheme or need to generate a range of monochromatic shades for a UI component. If you're building for the web, it checks everything against WCAG AA standards so you don't have to worry about accessibility audits later. It's a core part of the Vinkius catalog that turns a vague request for a 'blue theme' into a production-ready set of hex codes. You can shift the lightness or chroma of a color while keeping the rest of the palette stable, making it much easier to iterate on a design without starting from scratch every time. You can ask for specific relationships like triadic or analogous sets, or get a sequence of tints and shades that flow naturally. This removes the manual work of hunting for the right hex codes and replaces it with a system that follows professional design rules. ## Tools ### get_harmony_palette Creates a palette based on traditional color theory rules like complementary or triadic. It helps you find balanced color relationships quickly. ### get_monochromatic_shades Produces a range of tints and shades from a single hue. Use this to create depth in your UI without introducing new colors. ### get_attribute_variation Changes one color attribute like lightness while holding others constant. It lets you tweak a specific color's feel without breaking the palette. ### get_accessible_palette Generates a palette where every color is guaranteed to pass WCAG AA contrast standards. This makes it easy to build accessible web interfaces. ## Prompt Examples **Prompt:** ``` Generate a complementary palette starting from #3498db. ``` **Response:** ``` Here is a complementary palette based on your starting color: * **Primary:** #3498db * **Complementary:** #db7534 These colors provide a balanced contrast while maintaining a vibrant feel. ``` **Prompt:** ``` Create 5 monochromatic shades for #2ecc71. ``` **Response:** ``` I've generated 5 monochromatic shades for your green: * #2ecc71 (Base) * #27ae60 * #a8e6cf * #1e8449 * #d4efdf These provide a nice range of depth for your UI components. ``` **Prompt:** ``` Generate an accessible palette starting with #e74c3c with a contrast of 5.0. ``` **Response:** ``` Here is an accessible palette starting with #e74c3c that meets your contrast requirements: * **Base:** #e74c3c * **Contrast 1:** #ffffff * **Contrast 2:** #000000 This ensures your design is fully WCAG AA compliant. ``` ## Capabilities ### Generate WCAG-compliant palettes Creates color sets that meet accessibility standards for web content. ### Create color harmonies Builds balanced palettes based on complementary, triadic, and analogous rules. ### Produce monochromatic shades Generates a range of tints and shades from a single base hue. ### Adjust color attributes Modifies lightness or chroma while keeping other color properties constant. ## Use Cases ### High-contrast button for a government site A designer needs a high-contrast button for a government site. They ask the agent to find a red button that passes accessibility tests. The agent uses `get_accessible_palette` to provide a safe, compliant hex code. ### Warm triadic palette for a bakery A brand stylist wants a warm, triadic palette for a bakery. The agent uses `get_harmony_palette` to generate a balanced set of colors that follow established color theory rules for a cohesive brand identity. ### Consistent gray sidebar A developer needs a range of 5 grays for a sidebar. The agent generates monochromatic shades using `get_monochromatic_shades` to ensure a clean, consistent look that doesn't introduce unnecessary new colors. ### Adjusting a brand's signature blue A UI designer wants to make a specific blue lighter but keep its intensity. The agent uses `get_attribute_variation` to adjust only the lightness, ensuring the brand's signature blue stays recognizable. ## Benefits - Stop guessing if your buttons are readable. The `get_accessible_palette` tool ensures every color pairing meets WCAG AA standards for the web, making it easy to build inclusive interfaces. - Build balanced designs with `get_harmony_palette`. It uses actual color theory to find complementary and triadic relationships that look right and balanced to the human eye. - Create consistent depth with `get_monochromatic_shades`. It helps you build out UI components using a single hue for a clean look that doesn't overwhelm the user. - Tweak specific vibes with `get_attribute_variation`. You can adjust lightness or chroma without messing up the rest of your color scheme, allowing for precise design control. - Get accurate results with OKLCH math. This Connector ensures that colors look perceptually uniform to humans, avoiding the common issues found in standard HSL values for web design. ## How It Works The bottom line is it turns abstract design requests into production-ready color palettes. 1. Provide a base hex code or a specific design goal like a warm triadic theme. 2. The Connector calculates the color relationships using OKLCH math for perceptual uniformity. 3. You get a list of hex codes that are ready to drop into your CSS or design file. ## Frequently Asked Questions **Can the Palette Generator MCP help me make my website accessible?** Yes, it's perfect for that. It generates palettes that meet WCAG AA contrast standards, so you can be sure your text and buttons are readable by everyone. **Does it use standard color theory?** It does. It can generate complementary, triadic, and analogous palettes based on established color science rules. **Why is it better than just picking colors manually?** It uses OKLCH math. This ensures that different colors look equally bright to the human eye, which is much harder to do manually or with basic HSL values. **Can I get different shades of the same color?** Yes, it can generate a range of tints and shades from a single hue. This is great for creating consistent UI elements like buttons and backgrounds. **How do I make sure my colors look good together?** The Connector has a specific tool for color harmonies. You can ask your agent to create a triadic or complementary palette to ensure the colors are balanced. **What is WCAG AA compliance?** It's a standard for web accessibility. This Connector ensures the colors it picks for you meet those requirements so your site is usable for people with visual impairments. **What is OKLCH and why does it matter?** OKLCH is a perceptually uniform color space. Unlike RGB, changes in lightness feel consistent to the human eye regardless of the hue. **How can I ensure my palette is accessible?** Use the `get_accessible_palette` tool. It calculates contrast ratios to ensure all colors meet WCAG AA standards. **Can I use custom color angles?** Yes, by using `get_harmony_palette` with the 'custom' harmony type and providing specific angles.
