Perception, Colour & Language

It was red, yellow and blue when I were lad.

Broken Britain.

Woops, that's what I meant. I'll edit.

Side note – there are colours possible on your computer screen that are impossible to print using a regular printer, because the gamuts of RGB and CMYK colourspaces don't match up.

Yes, I keep having to explain this to people at work.

Has anyone else noticed that the gilets jaunes are more like gilets verts?

I don't have any colour dysfunction (that I'm aware of) but I do seem to have trouble with my blues and greens, compared to other people. I was disturbed to find most people thought a car I used to own was green; to my eyes it was blue. A bluey green for sure, but defo on the side of blue. Paperwork confirmed green. Weird.

Don't know how significant or scientific this test is, but it doesn't take long (I have normal colour vision apparently)

One of my cars that I thought was dark blue used to look green from a distance. When walking back to it after a dog walk I'd have trouble picking it out.

I also have normal colour vision.

There was just one that I wasn't too sure of. But at 74 year old I'm happy with the result.

INT21.

My brother-in-law has a colour blindness but I don't know what. He says the London Underground tube map isn't very clear, purple Met, brown Bakerloo, dark blue Piccadilly lines all blur into one colour.

Have we touched on people who have beyond-normal colour vision? There are a few about who can see further into the ultraviolet than most of us.

Like this guy, who after cataract surgery can see more colours than the rest of us us (though his what he actually 'sees' is of course within the same colour range - i.e. he can perceive further into the spectrum, but ultraviolet still looks like violet rather than The Colour Out Of Space) http://www.komar.org/faq/colorado-cataract-surgery-crystalens/ultra-violet-color-glow/

So I'm not colour blind. Good to know.

Isn't it still red, blue, green ?

The three colours used to generate what we see on out monitors and TV sets.

For additive colour mixing yes. Not for mixing paint.

Interesting and long wikipedia article on blue and green in various languages, with examples.

Somebody put some serious work into that. A good read.
