Free online color palette generator: build harmonious HSL color schemes, lock swatches you like, and export HEX or CSS variables. No signup required.
First time here? Choose a base color or generate randomly Your input is processed locally and disappears when you close the tab.
Every strong design, website, or brand begins with a cohesive set of colors. Our free Color Palette Generator builds harmonious schemes from real HSL color theory, so the swatches you get genuinely work together instead of clashing.
Choose a base hue, set anywhere from two to twelve colors, and switch between complementary, analogous, triadic, and monochromatic harmonies — or hit random mode for fresh inspiration. As a color scheme maker it lets you lock the swatches you love and regenerate the rest until the combination feels right, making it a fast color combination tool for UI kits, presentations, and social graphics. Copy any HEX value with one click, and when you're building a design palette or brand colors, export the whole set as ready-to-use CSS variables or JSON.
Everything is generated in your browser — no accounts, no uploads, and nothing about your palette ever touches a server. Keep the momentum going with the Gradient Generator to blend those colors into smooth backgrounds, the CSS Box Shadow Generator to add depth to your components, or the CSS Minifier to compress the finished stylesheet before you ship.
