Pick and convert colors online free with FreeToolBox — choose any color from the visual color picker and instantly get its HEX, RGB, HSL, HSV, and CMYK values. Whether you're a web developer matching brand colors, a UI/UX designer building a color palette, or a graphic designer who needs to convert between color models, our Color Picker gives you all the formats you need in one place. You can also enter a known HEX or RGB value and see the exact color it represents, making it easy to verify and convert color codes across formats.
The tool runs entirely in your browser — no data is sent anywhere. It includes a color harmonies generator to find complementary, analogous, triadic, and split-complementary colors, helping designers build balanced palettes. Copy any value with a single click. Completely free, no account required.
HEX (#RRGGBB) is a hexadecimal representation used in CSS and HTML. RGB (Red, Green, Blue) uses values 0–255 for each channel and is widely used in programming and design software. HSL (Hue, Saturation, Lightness) is often more intuitive for designers because adjusting saturation and lightness gives predictable results.
Modern browsers (Chrome 95+, Edge) support the EyeDropper API, which lets you sample any pixel color from anywhere on your screen. Click the eyedropper icon in the tool if your browser supports it.
CMYK (Cyan, Magenta, Yellow, Key/Black) is the color model used in print design. If you're preparing assets for print media, you'll need CMYK values rather than the RGB/HEX values used for screens.
After picking a color, the tool generates a set of color harmonies — complementary (opposite on the color wheel), analogous (adjacent), triadic (equally spaced), and more. Click any swatch to load that color and get its values.
