RGB()

Category: Text Formatting

Syntax: RGB ( red; green; blue )


Parameters:

redAny number or numeric expression containing a value ranging from 0 to 255.

greenAny number or numeric expression containing a value ranging from 0 to 255.

blueAny number or numeric expression containing a value ranging from 0 to 255.

Data type returned: Number

Description:

Returns a number that represents a color.

To calculate this integer, the red, green, and blue values are combined using the following formula:

 (red * 2562) + (green * 256) + blue


Use the RGB() function in conjunction with the TextColor() function to format text.

If a number above 255 is supplied as the parameter, the formula in the example still computes a result. If the result of the formula returns a value above the expected 0 to 16777215 range, the Mod (result; 16777216) is used to map the result into the expected range. So RGB (255; 255; 256), which returns a value one higher than white, returns the color black, just as 0 does.

Table 6.1 lists the RGB values of some common colors.
