The Hue/Saturation command adjusts the hue (color), saturation (purity), and lightness of the entire image or of individual color components in an image. Use the Hue slider to add special effects, to color a black and white image (like a sepia effect), or to change the range of colors in a portion of an image.
What is hue, saturation, brightness and luminance?
Hue is therefore the actual color. Brightness refers to how much white (or black) is mixed in the color while Saturation indicates the amount of grey in a color. A saturation value of 0 indicates mostly grey while 100% luminosity (or L = 255) is white ( see charts ).
What is the difference between saturation and brightness?
Saturation is the intensity of a hue from gray tone (no saturation) to pure, vivid color (high saturation). Brightness is the relative lightness or darkness of a particular color, from black (no brightness) to white (full brightness). Brightness is also called Lightness in some contexts, in particular in SQL queries.
