Hue vs Saturation
In RGB model of colors, a specific color is uniquely given by three attributes of the color. Those are Hue, Saturation, and Value.
Hue
Hue refers to a specific basic tone of color or the root color and, in a rough definition, can be considered as the main colors in the rainbow. It is not another name for color as colors are more explicitly defined adding with brightness and saturation. For example, blue can be considered as a hue, but with the addition of different levels of hue and saturation many colors can be created. Prussian blue, navy blue, and royal blue are some commonly known colors of blue.
Hue spectrum has three primary colors, three secondary colors, and six tertiary colors.
Saturation
Saturation is the measure of the strength of hue included in the color. At maximum saturation, the color is almost like the hue and contains no grey. At the minimum, the color contains the maximum amount of grey.
What is the difference between Hue and Saturation?
• Hue is a root color identified and can be roughly taken as the primary colors of the rainbow.
• Saturation is the strength of the hue present in the color ranging from grey to the original root color.
