Josef. There was also a older version of this model that used gspca and although it add several color controls the end result was pretty much the same, very bad colors: http://lists.berlios.de/pipermail/linux-uvc-devel/2009-August/005072.html
So I would say that the newer model uses the same or similar sensor/optics, and that the resulting picture ends up overexposed or with a gain increased in such a way that produces that sort of washed colors (low contrast). This can indicate a low quality/low sensitive cmos sensor (and probably also low quality plastic optics). With a better sensor (CCD or high quality cmos) smaller increases in gain and exposure would be enough to produce a good image, even in low light. It can also be that the firmware that controls these parameters is just bad :-( You can however try to reduce the fps value, this may (depending on the firmware) increase the exposure time and reduce gain producing a little better image (at least in some cameras I've tested reducing fps makes for a brighter image).
