Are Cats Color Blind?

[samiur]

When you look at a rainbow in the sky, you see shades of red, orange, yellow, green, blue, indigo, and violet. Do you ever wonder what your cat sees when he looks at a rainbow? Can your feline friend distinguish the same range of color that you do? Does he see bands of black and white? Do the colors look blurred?

Cats have done cells so can distinguish colours. However, they have about one tenth as man0ny as humans (they make up for it with far more rod cells). Therefore, their colour perception is not as acute as that of humans, but their depth and movement perception and night vision are far superior.

*cone cells (bloody auto correct).

someone must have done this. - Colin Blakemore did a lot on cats visions which had had the animal rights people going around trying to burn down his house
wd pussy see the orange flames? yes probz

some animals have an extended palate ( flies, insects) - I am not sure if an mammals do. I am not sure if mammals can see extra frequencies but not sense ( no I think)

Chickens have coloured oils in their cones to colour code

BUT - -- of course mummy cats dont teach young cats that is blue, and that is red....

BUT Newton felt when he 'did' the rainbow that there should be 7 colours because 7 was a sacred number so.... he invented Indigo as a new colour. (*)Newton was sure after Opticks that if he thought about and prayed about the Bible, God would reveal all - or alot. This was standard 1680 theology ( think and pray, God wd foop you on a direct line forget saints and popes)

so we had seven. Japanese have three, clearly there has to be spectrum overlap. This is done a lot by Trevor Roper Through Blunted sight. - Big seller in the 60s and 70s

but this is perception rather than frequency of EM radiation

Another is Colour in Nature

BUT what about in the past - Homer and wine dark seas?
oir Homer and rosy-fingered dawn ( porphyro-dactylos)

Have fun

[Peter Pedant]

Newton got heavily into numerology
the importance and significance of numbers in the Bible

Was the temple 7 cubits long? well if it was , then it was God's will. We dont do any of that now. Newton spent about 20 y on this

we dont do this side of Newton - as you know well it is a bit mad

are you new? You have to wade thro some mainstream gormless answers to get to some meat. I looked and thought - AB gormlessness wasnt that bad was it? yes

Some on Goethe ( and colour perception)

the books on colour perception ARE expensive as they are produced to such high specs

No, cats are not colorblind. They have dichromatic vision, meaning that they see colors but not as vividly as humans. Cats see blue and green better than other colors because those are the colors that contrast the most against their yellow retinas. This is why many cats seem to be attracted to colorful ribbon or yarn toys.

They see leprechauns and a pot of gold.

Welcome to Answerbank samiur. This is predominantly a UK site (I assume from your spelling you are American).

Your question has certainly attracted some engaging responses. For example when Peter refers to rosy and wine-red he is quoting a translation of the original Greek. I wonder if modern Greek rainbows have 7 colours - can anyone enlighten me?
