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
);
The return value is the resultant RGB color.
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.
For information about using color values in a color palette, see the descriptions of the PALETTEINDEX and PALETTERGB macros.
The RGB macro is defined as follows:
#define RGB(r, g ,b) ((DWORD) (((BYTE) (r) | \
((WORD) (g) << 8)) | \
(((DWORD) (BYTE) (b)) << 16)))
