> E.g. in Windows, when specifying color value using COLORREF they use the BGR format 0x00bbggrr. Wait a little bit... isn't Windows little-endian [1]? Following the link in that sentence: > typedef DWORD COLORREF; > 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. Given that Windows is and has always been little-endian, the byte order of a COLORREF is red first, then green, then blue, that is, the order is RGB. So the reason for BGR can't be Windows' COLORREF.
