Return Value
The red, green, blue (RGB) color value that determines the color of the specified element indicates success. Zero indicates failure. To get extended error information, call GetLastError.
Remarks
Windows CE 1.0 and 1.01 only support a 2-bit gray scale palette, so GetSysColor returns a palette index rather than an RGB value. Windows Embedded CE graphic display interface (GDI) functions that accept a COLORREF structure can use either a palette index or an RGB value. However, if the application attempts to interpret the color value, be aware of this difference.
Windows CE 2.0 supports 2 bits per pixel (2-bpp), 4 bits per pixel (4-bpp), and 8 bits per pixel (8-bpp) color devices, and can logically support 32 bits per pixel device independent bitmaps (DIBs). In Windows CE 2.0, GetSysColor returns an RGB value.
System colors for monochrome displays are usually interpreted as shades of gray.
