Arguing over the color blue
#1
Crone made a mention recently that we here on the RVF would argue over the color blue. Turns out there's a good reason for that, we all perceive colors differently. Smiling http://www.bbc.co.uk/news/science-environment-14421303

Color does not actually exist... what exists is light


Excerpt: "colours you see may not always be the same as the colours someone else sees… as we see colour through our brains, not our eyes. Neuroscientist Beau Lotto explains.

Colour is one of our simplest sensations… even jellyfish detect light and they do not have a brain. And yet to explain lightness, and colour more generally, is to explain how and why we see what we do.

The first thing to remember is that colour does not actually exist… at least not in any literal sense. Apples and fire engines are not red, the sky and sea are not blue, and no person is objectively "black" or "white".

What exists is light. Light is real.
Yellow and blue illusion The grey tiles on the left look blue, and the grey tiles on the right look yellow

You can measure it, hold it and count it (well … sort-of). But colour is not light. Colour is wholly manufactured by your brain.

How do we know this? Because one light can take on any colour… in our mind.

Here's another example. If you look at the cubes to the right, notice the four grey tiles on the top surface of the left cube and the seven grey tiles on the equivalent surface of the right cube:

The grey tiles on the left look blue, and the grey tiles on the right look yellow


Once you've convinced yourself that these tiles are all physically the same colour (because they are), look at the next image down.

What's amazing is that now the grey tiles on the left look blue, whereas the same grey tiles on the right look yellow. The yellow and blue tiles of the two cubes share the same light, and yet look very different.

Colour is arguably our best creation, one that is created according to our past experiences..."

The story goes on in depth, with many more examples for those that are interested. So see, Crone, we could argue over the color blue in much greater depth if we really wanted to, and we'd still never come to a conclusion we all agreed with. That's because no two of us sees color the same. Smiling

See Ponder! Just another intellectual argument to add to your point. Class dismissed. Wink

He needs a tooth pulled, poor guy. His color perceptions might be a little off today. Smiling

Well Scrapbook Ms, I was only pointing to the obvious. You did post a wonderful picture. The water there is indeed spectacular! Beautiful beach. Looks like a great place to roast a hot dog.
But, it did little to further Ponders amazement about the qualities of light. I'm not smart enough to understand light waves and all that science, but I was hoping it would stir some back-and-forth so I might learn something.
That's all.
No harm, no foul. Maybe Ponder will do a re-set. Smiling

So if we dove to to 100 feet in the ocean and looked at the same reef, would we see the same colors?

Doesn't water have a refractory quality? I'm not a diver and have no idea.

(I once knew a guy who went to the Brooks School of Photography in Santa Barbara, California. A four year curriculum, with some liberal arts squeezed in. He said that about 3 of those years was the study of light. I'm not sure, but I don't think he was joking)

The study of light was the best part of physics when I studied it. It was the reason I took no more physics though. The damned stuff confused the best minds, so I came to the conclusion "what the hell am I doing here?" Quantum mechanics sealed the deal. Photons are a bitch. Wave, particle, and when it became both (or even something else) I simply lost my mind. String theory came later. Anti-matter, negative energy and an equation that eliminates time (and cause and effect) too! AAAAUGH (Monty Python has interpreted this) ...

I prefer mauve.

Yea.
I discovered too late that Larry's cry of "When I drink, everybody drinks!" means "when I drink everybody pays".

And now we've done it, Ham. Hijacked the damn thread again.
