Alternatively, we might find that colors contain some information that raw grayscale values cannot capture. Most often, images come in the conventional RGB color space, where every pixel in the image gets an intensity value for its apparent Redness (R), Greenness (G), and Blueness (B). However, OpenCV offers a whole range of other color spaces, such as Hue Saturation Value (HSV), Hue Saturation Lightness (HSL), and the Lab color space. Let's have a quick look at them.
