Return Value

Type: Type: DWORD

The function returns the red, green, blue (RGB) color value of the given element.

If the nIndex parameter is out of range, the return value is zero. Because zero is also a valid RGB value, you cannot use GetSysColor to determine whether a system color is supported by the current platform. Instead, use the GetSysColorBrush function, which returns NULL if the color is not supported.

Remarks

To display the component of the RGB value, use the GetRValue, GetGValue, and GetBValue macros.

System colors for monochrome displays are usually interpreted as shades of gray.

To paint with a system color brush, an application should use GetSysColorBrush(nIndex), instead of CreateSolidBrush(GetSysColor(nIndex)), because GetSysColorBrush returns a cached brush, instead of allocating a new one.

Color is an important visual element of most user interfaces. For guidelines about using color in your applications, see Color.

Examples

For an example, see SetSysColors.
