To know the parameters of image color, one can use image processing software like Adobe Photoshop, GIMP, or other programming libraries like OpenCV in Python. These tools allow you to extract color information such as hue, saturation, and brightness. For programming, the RGB (Red, Green, Blue) model is commonly used to represent color parameters. For manual inspection, you can use a color picker tool to select a color from an image and view its hex code or RGB values.
