The value of a hue defines how bright or dark a color is.

A brightness control determines value: decreasing brightness adds shade (black), while increasing brightness adds tint (white).

Decreasing brightness adds shade and brings a color closer to black

In RGB and most computer systems, value is calculated as (R+G+B)/3.
