Actually, she can see all of the colours ranging from blue to green. We have cells in our eyes called cone cells that process colour, and despite the multitude of colours in the world, we have only three types of cone cells; red, green, and blue. The other colours we see are combinations of red, green, and blue. Dogs and cats, however, only have green and blue cone cells, so they can only process colours made from green and blue. Interestingly enough, there’s a type of shrimp that has a WHOLE FRIKKIN 16 TYPES OF CONE CELLS. DO YOU KNOW HOW MANY COLOURS THAT IS? THAT’S A LOT OF COLOURS.
Problem is, those 16 colors are the only ones it can see, because it’s brain isn’t sophisticated enough to do the cognitive mixing that leads to shades.
Huh never knew that bit. We’re talking about the mantis peacock shrimp, right? Those things can detect (I hesitate to say “see”) the polarization of light.
4 years late, but: colourblind does not specifically mean can’t see *any* colours. By human standards, only having the GB part of the RGB spectrum *is* being colourblind. Also, the scarf was Red, so she wouldn’t be able to see it properly. Also, matching colours when you can’t see the whole spectrum (from a human POV) sounds like it’d be a bit of a bitch (no pun intended).
That’s terribly speciesist, you know. I can see reds, despite being a cat. I just have problems with pastels due to a higher rod/cone ratio (50/50 as opposed to 70/30 for you two-leggers), nyao. Took me forever to figure out that those paint color thingies that they have in hardware stores show multiple shades instead of several squares of the same color…

…rant over.

So can humans, actually. It’s tricky, but we can do it.
And bees. It’s how they find the sun when it’s cloudy.
Just because dogs in general can see greens and blues doesn’t mean every dog can. Maybe Sweetheart actually IS fully color-blind!
I’ve read that the first cone more in the yellow range than the green range, but yeah, dogs can see more color than most people give them credit for.
Sweetheart could have monochromatic vision. All it would take is to have one defective cone, like humans with dichromatic vision do.

Hmm… is she blue-green colorblind, fully unable to see in colors, or just have trouble distinguishing pastels like I do, nyao?

You are either a very dedicated roleplayer or a very scientifically-minded cat.
Both! ^_^
Although I do admit that it’s kinda tricky to roll a d20 without thumbs, nyao…
