The RGB color model used in digital photographs re pro duc es colors using dif fer ing

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 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.
