Well, given that we define the portion of the electromagnetic spectrum that stimulates our retina as light, then certainly the varying wavelengths within it correlate with the gradations of visual perception we label as colour. A species that could detect X-rays might have an analogous term for the varying qualia within the X-ray spectrum they perceive.FBM wrote:Do varying wavelenghts of light = color? As we all know, the electromagnetic spectrum extends far beyond what the human eye can detect. Is X-ray a color?

Just to split a hair: In physics, "light" refers to any wavelength in the spectrum, not just "visible light".

Any ripple in the electromagnetic field is known as light. So are a sheep's lungs - but I'm not quite up on the physics of that.

Yeah we're more likely to wash our genitals, that's why. Well that and cooking an animal in it's own fat makes it tastier than scraping sinew from some scrawny skeletal thing from a famine zone.

Yes, as JimC already said. You can easily check this out, by making two holes in a piece of paper, so that you can see the squares in questions through the holes, while the paper covers the rest of the picture.Svartalf wrote:That's a trick question and they actually are the same in spite of not seeming so, right?MiM wrote:What is the difference in absolute shade between square A and square B?

Re: Does colo(u)r exist outside the brain
It's all in the brain. Some synaesthetes perceive red as the sound of a blackcurrant, so the brain is just making it all up as it goes along. Right bullshitter, the brain.

We can't even know if I perceive a shade of red the same as you do.
