"The HSV model describes colors similarly to how the human eye tends to perceive color. RGB defines color in terms of a combination of primary colors.
In situations where color description plays an integral role, the HSV color model is often preferred over the RGB model."

In RGB color system are co-related to the color intensity, and we know that you cannot distinguish color information from the intensity. Using HSV or Hue Saturation Value we can separate image luminance from color information. using HSV or Hue you can separate luminance of the image or frame.
