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
obvious 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.
