AN INTRODUCTION TO COLOR
In photography, red, green, and blue are
the primary colors. The secondary colors,
cyan, magenta, and yellow, are made from
combining the primary colors: cyan = blue
+ green, magenta = blue + red, and yellow
= red + green. The primary and secondary
colors are grouped in complementary
pairs: red and cyan, green and magenta,
and blue and yellow.
Knowing the complementary colors is very
important in color balancing. If the image
has a specific color cast, either subtracting
the color or adding its complementary
color will create a natural looking image.
Adding or subtracting equal parts of red,
green, and blue have no affect on the color
balance. However, changing two colors
equally has the same affect as the
opposite change with one color; +2 green
and +2 red is the same as -2 blue. The
greatest change in a specific color comes
by setting the color channels to their
opposite extremes. To make an image as
blue as possible, set the color channels to
+2 blue, -2 red, and -2 green.
