These are the listed camera controls:
control[0]: 0x98090b  auto black level compensation, 0:1:1, default 0
control[1]: 0x98090e  red balance, 0:1:63, default 8
control[2]: 0x98090f  blue balance, 0:1:63, default 26
control[3]: 0x980913  global gain, 0:1:255, default 64
control[4]: 0x8000001  green balance, 0:1:63, default 47

try setting the color balance (rgb channels) maybe you can improve the image.
There also seems to be some confusion on the real color matrix of BA81 format.

here: http://www.fourcc.org/rgb.php it states that the format is of
the order grgr... bgbg..., but V4L2 defines it with bgbg... grgr...,
I'm guessing that V4L2 is more accurate, in any case if you can't get
the colors right maybe we can try a little experience later :-)

I'm not sure about kopete, have you tried amsn ? It seems to have
better webcam support.
Skype, I think, only supports yuv formats, but since is not GPL I can
only recommend ekiga ;-).

Best regards,
Paulo
