Does colour only exist in our brain? Book argues it is simply a construct of the mind
Daily Mail ^ | May 22, 2015 | Ellie Zolfagharifard

Roses aren't red and violets aren't blue.

At least that's the premise of a new book, 'Outside Color', which puts forward the debate that colour is, in fact, an illusion.

Author Dr Mazviita Chirimuuta uses the book to explore the historical debates that suggest colour doesn't exist - at least not in the literal sense.

Light, however, does exist, and it's the mind that transforms that light into colour.

'Of all the properties that objects appear to have,'writes the University of Pittsburgh professor, 'colour hovers uneasily between the subjective world of sensation and the objective world of fact.'

Optical illusions, such as the blue and black dress that went viral this year, show how objects have colours that observers perceive differently.

All this goes to prove that the feminists are right, that no one woman is more beautiful than another. It is mere lookism. Hillary looks as desirable as Cindy Crawford. That a person can safely step in front of a bullet and it is only imagination that he is dead. Nothing is real, including that pot of gold. Everything is mental constructs.

So how do I know if I’m really taking the red pill?

Those quantities are compliments in a reflecting material. Colored glass can be anti-reflection coated, in which case there is no reflection, or at least very little, but even if the antireflection coating were perfect, the stained glass would still be colored the same way it would be perceived without the AR coating. Color is what happens when some parts of the visible spectrum are treated differently than other parts are, in such a way that the R/G/B ratios become different as perceived by human eyes.

They’re both red pills when you’re wearing rose-colored glasses.

I read the article, did not see a single reference to rods and cones. The physical nature of the difference between two separate light sense gathering cells is certainly a cause for something in light perception. Since the washout of color in night vision has a huge effect in actual experience, its absence in the article would seem to be more than an oversight...lol.

The pictures were also confusing as to how they represent the concepts. Differences in green show green is not real? Perceptually a difference in gray that is not when taken out of context is a measure of color? I would have appreciated the context of using impressionists to show color variability with the mind...but I didn’t write the book.

If you live in the world of science, this is true. And the atoms that constitute matter are mostly the space between elections, etc. Then in that world, humans are stimulus-response machines, natural law and morality are useless and relative, and God is dead. And the result is that people actually listen to protesters screaming about nothing but their raw emotion and drivel.

However, in the True world of the Soul, the sky is blue, the Trinity is real, and humans are in God’s image who live under God’s law.

"The whole argument is silly."

It wasn't considered silly by John Locke, "Father of Classical Liberalism"

who wrote An Essay Concerning Human Understanding.

And for a more scholarly treatment:

Well, there was a guy that walked around for months with a special viewer that caused him to see everything upside down. Guess what? After a month or two, his software was modified and he saw everything as upright.
And when he removed the glasses for the first time, everything “looked” upside down.

The "reprogramming" of his vision happened in a matter of days after donning the glasses. It should be noted that the glasses not only swapped up and down, they also reversed left & right. After the first transition he demonstrated proficiency by playing pool and riding a motorcycle among other feats.

The removal of his prismatic glasses caused him serious problems with headaches, disorientation, and vertigo which lasted much longer than the first transition into the "upside down worldview";, although he eventually did return to "right side up", which is in fact upside down on your retina.

The moral of the story?
"It's not nice to fool with Mother Nature!"

Reminds me of the CALVIN AND HOBBES cartoon in which Calvin’s dad explains to him how everything before 1950s was all black and white and then everything took on color.

Poor little confused kid! Hey, it even confused me for a while!

The color blue or at least a word for the color blue does not exist in ancient texts. Other colors are mentioned, but not blue.

If the color blue did not exist then, how can it exist now?

If color is, by definition, a visual phenomenon and it is only in the perceiving that that phenomenon is observable, then the perception of color CREATES the color, which would otherwise simply be an electromagnetic phenomenon.

This is basically the “tree falls in a forest” question with a visual rather than an aural component.
