From what I've read, dogs are red-green color blind and do not have very good detail vision (6X poorer than humans), but a much wider field of view (peripheral vision) and much better night vision than humans.
Hey bbkoo, pull your h%$d out of your a@@, just because on is color blind doesn't mean one doesn't have good eye sight. And as far as your comment about driviing at night, I would match my driving skills against yours any day, any night, any dusk or any dawn.
Now why don't you go and run along and think of some other annoying and stupid topic to post on. Maybe a topic you know something about.

Night time has very little to do with basic color blindness. Any person will have trouble distinquishing colors in dim light, not just people with the inability to see certain colors. We did a test on it in high school (a LONG time ago) using different colors of equal shades. As the lights were dimmed it got increasingly difficult to tell colors apart. The worst were red/brown/purple and green/blue. We had students leave the room and return to dim light and try to tell us the correct color of the object they were looking at or to choose a specific-colored object from a group. It didn't have to be very dark at all before the colors started to look the same.
well you learn something new everyday. i did not know that people could have colorblindness also. thanks guys ! it may come in handy someday. " that was a red light i ran officer ? i am colorblind. they all looked the same ! " hehe
The only problems I have with colors are matching clothing......and painting.......no probs w/traffic lights, signs etc.....I drive about 40,000 miles a year in my job.....and I have a spotless record :-)
Arachyd, exactly. The reason that we are unable to see colors in the night time is because we use our rods to see in dim light. Unlike cones rods do not contain pigments which are sensitive to color. People with color blindness are at no disadvantage in the dark, because entirely different neurons are used to see in dim light.
In most cases color blindness is not a big deal. About 1/10 people are color blind to some extent. It certainly doesn't mean that they can't drive and do things that anyone else couldn't.
