Explanation: 

Detailed explanation-1: -Therefore, a hue is the founding dimension of a color determined by wavelength; in short, hue is just the base color.

Detailed explanation-2: -Background. The perception of color is often described by referring to three dimensions of the color experiences: hue, saturation, and brightness. Hue refers to the color quality of the light and corresponds to the color names that we use, such as orange, purple, green, indigo, yellow, cyan, aquamarine, etc.

Detailed explanation-3: -Hue is described with the words we normally think of as describing color: red, purple, blue, etc. Value (lightness) describes overall intensity to how light or dark a color is.It is the only dimension of color that may exist by itself. Chroma (saturation) may be defined as the strength or dominance of the hue.

Detailed explanation-4: -Hue is more specifically described by the dominant wavelength and is the first item we refer to (i.e. “yellow”) when adding in the three components of a color.

Detailed explanation-5: -Hue. It is a property of chromatic colours. In simple words, it refers to the name of the colour, e.g., red, blue, and green. Hue varies with wavelength, and each colour is identified with a specific wavelength. For example, blue has a wavelength of about 465 nm, and green of about 500 nm.
