Click and drag the slider bar across the blue slider
strip to view a set of same-color shapes as they change hue on both the
black and the white maps of North Carolina.
Notice the difference in the apparent look of each color when placed
against a black vs a white background. Contrast and apparent saturation
of a hue tend to increase when placed against black and decrease when against
white. The dark blue, and red in this example, however, look more dull
against the black background. All other colors here appear brighter when
surrounded by black. |
