Specifying colors
You specify a color by specifying a number that represents the color. You can
specify the number explicitly or by using an expression that includes the
RGB
(r, g, b) function.
For the numbers and expressions that specify common colors, see Table 10-2
on page 315.
How the number is
calculated
The formula for combining color values into a number is:
red + 256*green + 256*256*blue
where the amount of each primary color (red, green, and blue) is specified as a
value from 0 to 255.
The
RGB function calculates the number from the amounts of red, green, and
blue specified.
