The three parameters (or attributes) in the HSV are known as Hue, Saturation, and Brightness (or 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.

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.
