RGB macro

The RGB macro selects a red, green, blue (RGB) color based on the arguments supplied and the color capabilities of the output device.

COLORREF RGB(
BYTE bRed, // red component of color
BYTE bGreen, // green component of color
BYTE bBlue // blue component of color
);

Parameters
cRed Specifies the intensity of the red color.
cGreen Specifies the intensity of the green color.
cBlue Specifies the intensity of the blue color.

Return Values
The return value is the resultant RGB color.

Remarks
The intensity for each argument is in the range 0 through 255. If all three intensities are zero, the result is black. If all three intensities are 255, the result is white.

The RGB macro is defined as follows:

#define RGB(r, g ,b) ((DWORD) (((BYTE) (r) | \
((WORD) (g) << 8)) | (((DWORD) (BYTE) (b)) << 16)))
