or am i just being weird?

Answer 1

We can test if we see colours normally by doing a simple colour vision check using the Ishihara charts. Try it yourself!

Answer 2

Well, many of us do see different colours, as some people are colour-blind, while others have problems with eye circulation, issues with the retina or macula, or the rods and cones, or the optic nerve. Many people can close one eye and see slight differences in color perceptions within each eye.

However, to directly address your question, we know that the colors are the way they are because of scientific instruments that have measured wavelength, in addition to knowing that some colors are dark, transparent, or bright. Yet, psychologically, we associate colors with various likes and dislikes, and we base these feelings upon early childhood experiences and inbourn biology that protects oneself from the dangers found about within the wild. Birds instinctively know that some brightly coloured berries are poisonous. Similarly, mankind instinctively knows that specific colours represent potential hazards.

Answer 3

Brilliant question, I hope this answers it for you. I used to think this too. However, I now believe we all see the same colours, and I think the proof is those colour charts. They were round with different coloured dots in them. Here's a link, and if you scroll down to Figure 9, thats what I'm trying to describe: http://www.sapdesignguild.org/resources/accessibility_res/vision_physiology.asp

Answer 4

the brain is only interpreting (seeing) the wavelength of light coming from the object. this wavelength would be the same no matter who was looking therefore the input is the same. Brain "processing language" has got to be individual, but we are taught that whatever result we get from a particular wavelength input is called a particular colour.

Answer 5

I've always wondered that too. Maybe what I see as blue is what you see as red.

I have this weird idea. Maybe everyone like the same color, but people see colors differently, which is why people have different favorite colors.

Answer 6

This is entirely true and impossible to argue against.

Answer 7

wow your as deep minded as me, im always thinking of things like that, i thought i was the only one lol, great question though, shame no one can answer it hun :)

Answer 8

this is a good point, it has been made by scientists before. you cannot argue against it.

Answer 9

Just because it isnt,

Answer 10

i thought that before.
we'll never know
