Color Balance
These settings let you control the relative intensity of the individual colors of
the additive color model (red, green, blue).
Note
The position of the color bar also affects the complementary color relation-
ship. Red, for example, is printed using magenta and yellow toner, so in-
creasing the level of red also decreases the level of cyan.
