Color Chooser Dialog Window
You may alter the chosen color's RGB value by selecting two or three Step Colors. Using
multiple step colors will present you with a greater range and variety of colors to choose
from.
• For instance, if you choose to modify your Start Color with two steps, then Step
Color 1 will change its values on the X (horizontal) axis and Step Color 2 will
change its values on the Y (vertical) axis.
• If you modify your Start Color with three steps, Step Color 1 will remain
the same. However Step Color 2 and Step Color 3 will form an imaginary 'X'
and their values will change on opposing diagonal Y axes.
