To find color codes from an image, you can use various online tools or software. First, upload the image to a color picker tool. The tool will analyze the image and provide you with color codes such as RGB, HEX, CMYK, etc. Common tools include Adobe Color, Coolors, and ColorZilla. Alternatively, some image editing software like Photoshop has a color picker feature built-in. You can simply click on the color you want to extract the code.
