is actually a combination of all When light
passes
through a wedge-shaped glass, called a prism, the beam of white light
is bent and separated into bands of
,
called the color spectrum. The colors of the spectrum always appear
in the same order: RED, ORANGE,
YELLOW,
GREEN,
BLUE
AND
VIOLET.
A rainbow is a natural example of a spectrum. Rainbows occur when
-light is bent by water, oil, or a glass prism. You can find rainbows
in the
,
in the spray
from a garden hose, or in a puddle of oil in a parking lot.
Objects absorb
some
waves of light
and reflect others. An
looks red because it reflects red
waves and absorbs the rest of the colors.
Special color receptors in your
detect these red
light waves, and your
then reads the light as being a certain color. The light enters your
and travels to your retina, at the back of your
.
There two types of cells react to the light. One type receives impressions
of lightness and darkness. The other type receives color.
Colors
really don't change, but your ability to distinguish between them does.
When you are looking at
,
your
can sometimes
fool you!
There are
many ways to use color- Artists
reproduce
them as they see them. The placement of
/
and
/
colors create illusions of depth
. Color can also create a sense of movement.
