The tool uses the Delta E 2000 (ΔE2000) algorithm to compare your input color against a curated database of named colors. It calculates perceptual color difference and returns the closest match with a similarity score, along with hue classification and intensity analysis. Our guide on finding a color's name from its hex code explains why simple RGB matching gets this wrong.
You can input colors in HEX format (#3498db), RGB format (rgb(52, 152, 219)), or use the color picker. You can also upload an image and click to pick colors, or use the eyedropper tool to sample colors from your screen.
The match score shows how similar your color is to the named color in the database. 100% means an exact match, while lower percentages indicate the closest available name. The algorithm considers human color perception, not just mathematical RGB distance.
Similar colors are the next closest matches from our database. Color harmony shows complementary, analogous, and triadic colors that work well with your input color, helping you build cohesive color schemes for design projects.
Yes. You can copy the color name, HEX code, or RGB values with one click. The tool works completely in your browser, so your color data stays private and is never uploaded to any server.
