The COLORREF value is used to specify an RGB color.

typedef DWORD COLORREF;
typedef DWORD *LPCOLORREF;

Remarks

When specifying an explicit RGB color, the COLORREF value has the following hexadecimal form:

0x00bbggrr 

The low-order byte contains a value for the relative intensity of red; the second byte contains a value for green; and the third byte contains a value for blue. The high-order byte must be zero. The maximum value for a single byte is 0xFF.

To create a COLORREF color value, use the RGB macro. To extract the individual values for the red, green, and blue components of a color value, use the GetRValue, GetGValue, and GetBValue macros, respectively.
