There are, however, many other color systems each with their own advantages:

• RGB is the most common as our eyes use something similar, but keep in mind that the OpenCV display system uses BGR colors.
• The HSV and HLS decompose colors into their hue, saturation and value/luminance components, which is a more natural way for us to describe colors. You might, for example, dismiss the value component, making your algorithm less sensitive to the light conditions of the input image.
• YCrCb is used by the popular JPEG image format
• CIE Lab* is a perceptually uniform color space, which comes handy if you need to measure the distance of a given color to another color.
