Colors

[Hue], [Brightness], and [Saturation]

Color has three elements: hue, brightness, and saturation. These are referred to as three attributes of colors

and all colors are created by combinations these elements.

You can adjust the hue, brightness, and saturation in 19 levels.

What is hue?

Everybody has an idea of what "hue" an object has, for example, an apple is red, a lemon is yellow, and the

sky is blue. "Hue" is the tint by which the color of an object is classified as red, yellow, blue, etc.

What is brightness?

"Brightness" is the degree of lightness in a color, as compared with another color, which makes it a light color

or a dark color. For example, when comparing the yellow of a lemon and the yellow of a grapefruit, it is ob-

vious that the yellow of the lemon is brighter. But what about when comparing the yellow of a lemon and the

red of a bean? Obviously, the yellow of the lemon is brighter. "Brightness" is this degree of lightness that

enables comparison regardless of the hue.

What is saturation?

What makes the difference between the yellow of a lemon and the yellow of a pear? By saying that the lemon

is a more vivid yellow and the pear is a duller yellow, the difference between the two colors is stated in terms

of "saturation", as opposed to "brightness". As opposed to hue and brightness, "saturation" is the charac-

teristic that indicates the degree of vividness.
