red (1 byte): An unsigned integer that specifies the intensity of the color red. A value of zero specifies that there is no red. Larger numbers specify a more intense red than smaller numbers.
green (1 byte): An unsigned integer that specifies the intensity of the color green. A value of zero specifies that there is no green. Larger numbers specify a more intense green than smaller numbers.
blue (1 byte): An unsigned integer that specifies the intensity of the color blue. A value of zero specifies that there is no blue. Larger numbers specify a more intense blue than smaller numbers.
fAuto (1 byte): An unsigned integer whose value MUST be either 0xFF or 0x00. If the value is 0xFF, the values of red, green, and blue in this COLORREF SHOULD<208> all be 0x00. If fAuto is 0xFF, this COLORREF designates the default color for the application. An application MAY<209> use different default colors based on context. This documentation refers to the COLORREF with fAuto set to 0xFF as cvAuto.
