Human Perceptions and the color Blue.

[ThePoodonkis]

Me and some friends were discussing this yesterday.
We were looking through a dictionary and we came across the definition of Blue.

Blue = The color of the sky or deep sea.

Alright, but what does the sky or sea look like?
I know how I perceive blue, it's a neat color.

But here's the thing, is everyone's vision of blue the same?
Is it possible that if I saw blue through your eyes; I'd see what I define as orange?

So, I want to know. What does blue (or any color for that matter) look like to you?

How would you describe this to someone who has never seen this color before?

 

[Monkfish Acc.]

Blue is the color of the midday sky behind the clouds.

That works, right?

To ruin the arguement an object that appears blue reflects only blue light (or a mix of close light colours to make mixed blue type colours) but I agree it is interesting to ask if people perceive it the same way. Colour blind people I have known sometimes describe that without their contact lenses they see colours differently from normal.

I've wondered that too, but it seems unlikely we'll ever know either way.
It's even possible that you see blue as a colour that my mind has never seen, and that my view of blue is a colour that doesn't exist for you.

Yeah, interesting question, one that I have pondered on myself, but it is impossible to know.

 

[TheRightToArmBears]

I think everyone must have pondered on this. Unfortunately, it is impossible to find out.

... yeah most colours look like numbers to me and vice versa... actually my fav blue I think was #00004C or something

I don't get why people find this interesting. The thought cannot be proven or even expanded upon beyond that inital "what if" sentence, and even if it could it doesn't change anything. Most tedious philosophical question ever. Here's a transcipt of the entire discussion:

Scenario 1
Guy 1: What if the color blue looks different for you than it does for me?
Guy 2: Interesting.
Guy 1: Agreed.

Scenario 2:

Guy 1: What if the color blue looks different for you than it does for me?
Guy 2: It doesn't.
Guy 1: How do you know? It can't be proven!
Guy 2: I guess.

Snore.

Does it matter? Things still reflect light with a wavelength of 610 to 670 THz. However our brains perceive it, that's not actually changing. "The colour of the sky or deep sea" is a useful definition, because people will have seen at least one of those things in their lives, and what actually matters is that people know what you're talking about when you say "this shoe is blue".

You may as well ask "what does E flat sound like to you", or "how does sugar taste". It's the same thing.

The way I see it, among people without defects in either their eye or the part of the brain that processes sight, there is no reason for different observations to occur. Scientists have a pretty good idea of how the eye receives info and how the brain processes it. The same goes for the E flat and the sugar.
I may be wrong, so don't quote me on this.

That works, right?

hahaha not if you live in england, here it is sort of greyish whenever there is less than 100% cloud cover.

Blue is the color of a man's certain area after it has been kicked hard...

Dammit, you're right.
Uh... Blue is the colour of... The majority of PS2 game cases under their cover art. How about that?

 

[vulgarshudder]

I think unless you're colour blind blue looks...blue....like that's why you do those tests with the coloured dots...

 

[Lord George]

How do I know you concept of colour is the same as mine in the first place maybe I see colours as abstract feelings each giving out different emotions?

 

[MilesPrower]

Blue...All it seems to me is look like well blue!Or in some cases....Sonic The Hedgehog!

 

[xxDarlenexx]

It's almost mind boggling that no two people might see the same color the same way.

And pyschologically speaking blue means calm. For some reason research showed blue (especially light blue) has a calming effect on people. I remember all the walls in my old elementary school were blue, probably to try and curb our little monster impulses.
