COLORREF
The COLORREF value is used to specify an RGB color.
typedef DWORD COLORREF;
typedef DWORD* LPCOLORREF;
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.
// Color constants.
const COLORREF rgbRed = 0x000000FF;
const COLORREF rgbGreen = 0x0000FF00;
const COLORREF rgbBlue = 0x00FF0000;
const COLORREF rgbBlack = 0x00000000;
const COLORREF rgbWhite = 0x00FFFFFF;
