Hue
The RGB color model used in digital photographs re pro duc es colors using dif fer ing
amounts of red, green, and blue light. By mixing two colors of light, a variety of
dif fer ent colors can be pro duced. For example, red combined with a small amount
of green light produces orange. If red and green are mixed in equal amounts, yel-
low re sults, while a smaller amount of red produces a yel low green. Mixing dif fer ent
amounts of red and blue light pro duc es col ors rang ing from a red dish purple through
pur ple to navy, while mixing different amounts of green and blue light produces col ors
rang ing from em er ald to turquoise. (Add ing a third color of light results in lighter
hues; if all three are mixed in equal amounts, the results range from white through
gray.) When this pro gres sion of hues is ar ranged in a cir cle, the re sult is known as a
color wheel.
