Could there be other colours?

i swear spiders see different colours? x

Are you sure they dont just see our blue as green or something? Not entirely new colours, just mixed up ones.


Studies have shown that you're never more than ten feet away from a spider.

A teacher I had many years ago actually believed that we all saw different colours from each other.

What we called 'green' would be different for each person. The grass is green, yet someone's colour green could be someone elses pink and we'd never know?

That always really confuses me because my brothers colour blind and I always wondered how they found out because like he sees brown as green but wouldn't he call green brown then? They also think I'm colour deficient and I don't get how they know that too

But back onto the thread topic - I don't think there are any more colours that we can see or they would've been seen already.

I had this exact discussion with somebody a while ago as well as the original thread topic and I was amazed because he had the same thoughts as me! I've always imagined the possibility that different people see each colour differently. Like your example of grass, we all call it green because we have been told that that colour (whatever it is) is green. However you could easily see it as what I call blue.

Also regarding extra undiscovered colours; it's simply unimaginable. Everything you ever think about, has a colour and you can't imagine something as specific as a colour if you have never seen it before. When you think about a colour like red or yellow, you probably always automatically associate it with an object.

The ultimate question is, what is a colour? You can't just think about a colour without it either being the colour of a car, or a coloured piece of paper, or some paint. There is no specific object that can be referred to as colour.

I know I rambled a bit lot, I just love this discussion

There is essentially an infinite number of other colours that we cannot see. Our eyes see a very narrow band of the electromagnetic spectrum which we call the visible region. The whole spectrum theoretically expands indefinitely in both directions, although practically there's "only" around a few million billion (a rough guess) other "colours" that we cannot see.

This. This particular thread topic was on richard hammonds invisible worlds. xrays, infrared, ultraviolet. All, we cannot see, but are there all the time.

The colour spectrum that we can see - between black and white - are all that exist.

but black and white arent actually part of the spectrum, black is the absence of visible light and white stimulates all light receptors. the spectrum im pretty sure is between violet (thus the term "ultra violet," which is invisible light with wavelengths sorter than violet) and red (thus "infrared", as in invisible light wavelengths higher than red). visible color is only a small part of the spectrum of light. i guess you could say we have discovered new types of light (which includes x-rays etc), but we have never discovered a new color.

i swear spiders see different colours? x

some animals can see forms of light we cant, i think some birds can see infrared. but idk what it would look like.

wowwww i thought i was the only one who thought this, a few years ago i tried to explain this idea to my family but i think i must have just explained it really badly cos they didnt get what i was saying but i believe in this as well

on topicc i was thinking about this other day and i googled it cos there must have been someone who thought they discovered a new colour and hey hooo there obviously was, this guy reckoned he found a new colour which he called SQUANT and you can read all about it here, http://www.negativland.com/squant/story.html but i just couldnt be bothered to read it all tbh. apparently you have to download the plug in to be able to see it i think, but it turns out its just a lie. i'd love it to be possible to discover new colours, but i dont think it is

Not everyone see's the same colours as everyone else anyway I thought. My blues wont look exactly the same as someone elses in a lot of cases.
