Awesome, but if they were colour blind from birth, how do they know what red and green actually look like... :shiftyninja:

I'll take it one step further and ask:

How do we know what looks red and green to me looks red and green to you? :shiftyninja:

Is my red also your red?

The article is incorrect, dogs can see colour but they only have 2 colour receptors in the retinas of their eyes as opposed to our three. This means they see everything as a shade of blues greens and yellows, like a human with red colour blindness.
They have many many more rods in their eyes compared to us though which gives them a keen eye for movement and seeing in the dark.

(Offtopic I know but it always bugs me when I see that. Always telling people dogs dont see black and white xD)

[/quote]because the disect and examine dog eyes (from dead ones I assume xD) and see that they only have those 2 colour receptors compared to our three
I also imagine they can examine their eyes like they do with humans. Modern eye tests can tell exactly what sight issues you have without any input from the person, they can SEE whats wrong. Quite amazing really.

Scientists hire pirates (ones wearing an eyepatch) to jam a dog eye into the socket, then the pirate reports out the results of what he sees.

This would be so useful for my Dad, he is colour defective (can't tell the difference between red and green).

I try my best to guess at a clever sounding answer, and you pick the pirates one!

They can also wire up the dogs and monitor neuron signalling from each type of receptor when the dog is exposed to images tuned to stimulate particular sensors. They can can also monitor the activity of the vision centers of the brain with fMRI (functional MRI) scans.

Very similar to how they're mapping motor regions to decode how to use natural signalling and brain-machine interfaces to move bionic limbs.

A better feat would be creating glasses that would allow us to see outside the visible spectrum, like dogs and other animals. That's why they can see paranormal entities while we can't.

I'm colourblind, and from my perspective, its not all of a sudden [i]seeing [/i]red, or green, cos I see both everyday. Its the fact that at times I can't tell which is which. Particularly when red and green things are in proximity - whichever is most dominant tends to prevail. As an example, those trees that are leafy and have big red flowers? Yeah, I cant see the flowers, just lots of green. However, if I pull one of the flowers off and look at it, it looks red. Stupid eyes...

So yeah, bring these bad boys on I say! I'll have it in sunglasses and reading glasses thanks!

I think my kittens saw their dead 'grandfather' one night in the kitchen.

They were highly upset at [i]something[/i] invisible.

I have read about special glasses year ago, that supposedly lets one see other higher frequencies.
