Remarks

 

An RGB value is a long integer value in the range of 0 to &H00FFFFFF. It is used to specify a color.

The lowest three bytes of the value each specify the intensity of a primary color which combine to form the resultant color.

Byte 1 (lowest) represents the red component, byte 2 the green, and byte 3 the blue.  They can each take on a value in the range of 0 to 255.

Byte 4 (highest) is always 0.

 

When used with 3 parameters, the RGB() function creates an RGB value from the three component values.

 

When used with one parameter, this function translates a BGR value to its RGB equivalent by swapping the first byte with the third byte, and returning the result.

 

For example, the BGR value of red is &H000000FF. RGB() translates it to &H00FF0000.  Calling BGR() with that value converts it back to &H00FF0000.
