I'm not a vet, but my books say that ferrets can see red.  How well they
see other colors is unknown because of lack of testing.  I'm not sure
where the idea that ferrets have poor eyesight came from.  Dr. Fox says
that in ferrets trained to differentiate between striped and grey targets,
their visual resolution is 8.5 minutes of arc at 220 lux and 17.5 at 0.01
lux.  That doesn't sound so bad to me.
