Top 10 Illuminating Facts About Color 10. The Visible Light Spectrum Light is basically invisible energy traveling
through space. For us to see it, light must go through dense particles of dust, smoke
or water vapor in the form of clouds or mist. We can also observe it when it’s hitting
something hard like a tree, a hand or the moon and reflects back into our eyes. Other
than that it’s as if nothing’s there. Sir Isaac Newton discovered that when allowing
a beam of light to travel through a prism it refracts into colors that always go in
the same order: red, orange, yellow, green, blue, indigo and violet. Our retinas contain two types of light sensitive
cells, rods and cones. The rods are used to detect light intensity and brightness while
the cones are responsible for color vision. We have three types of cones capable of recognizing
red, green and blue. These are the primary colors, and combining any two will give us
the secondary colors of yellow, cyan and magenta. All these hues in different combinations and
intensities give us the many colors that we know and see every day. Let’s say that the entire electromagnetic
spectrum is the distance between New York and L.A., around 2500 miles. With that scale,
the visible light spectrum would be about one inch long. That’s how much of the world
we’re not seeing! 9. The Need for Darkness J.W. Goethe observed that by looking through
a prism color forms around darker objects against a light background. This coloring
always happens as a transition from white to black going through yellow and red, from
black to blue violet or from turquoise to white. Overlapping these two boundaries are
the secondary colors or inverted spectrum. Color tends to form as a contrast between
light and darkness. On one side we have warm colors such as red and yellow going from white
to black, and on the other we have cold colors like blue and violet that go in reverse from
black to white. When you watch a perfect sunset do you notice
what array of colors appear on the evening sky? The sun becomes reddish as it nears the
horizon, engulfing the landscape in an orange haze, while shadows become longer and longer
until they’re one and the same. Due to the angle of the sun, its light has to travel
through more of the lower, denser atmosphere. The color red is actually a dimming of bright
light traveling through much more stuff. If we turn around from a sunset we’ll see
the Earth’s shadow. The bright blue sky is gradually transforming into darker blue,
indigo and violet as it meets the horizon. The more light there is in the air the brighter
the blue. What we’re really seeing is the dark and emptiness of the cosmos as different
shades of blue through the white light of the sun! 8. Colored Shadows If we look at a window for a couple of seconds
and then close our eyes we’ll see its negative — a light frame with a dark exterior. This
experiment can be done with colored objects as well. Each color has a complementary one.
Red has cyan, green has magenta and blue has yellow. If you illuminate a vase with two sources
of light a short distance from one another, the vase will have two shadows. If one of
those light sources shines a red light the opposite shadow will turn red because red
light falls on it, but its own shadow will become cyan. If we could somehow isolate that
shadow from its surroundings and look at it on its own we’ll see that it’s actually
gray like a shadow should be, but in the context it’s an optical illusion. 7. What Color Do Objects Really Have? It all depends on light. Colored lights make
up the visible spectrum but objects are not made of light. Let’s say you have a green
shirt. You go outside and it’s still green. What happens if you go inside a room with
red light? What color is it then? Normally red and green combine to create yellow but
here we have a red light and a green pigment. Green pigment is made out of blue and yellow
dyes which don’t reflect red, so the shirt is black. It’s also black if it’s in complete
darkness, along with everything else that has no contact with light. For another example, what makes a banana look
yellow? When white light hits the banana all hues get absorbed except for yellow, which
is reflected back into our eyes. In a sense bananas are every color except yellow, because
we observe what’s reflected back at us. And what is everything but yellow? Its complementary
color, blue! A banana is theoretically blue! We say theoretically because in order to have
color we also need to have an observer. Color is not a property of an object; it’s merely
an interpretation of the mind based on invisible waves at different frequencies. 6. Pink If we look at a light color wheel we see both
the primary and secondary colors in alternative order. Each secondary color is produced by
combining the neighboring primary colors. By combining red and green light we get yellow,
green and blue equals cyan and if we combine red and blue we have pink. Did you ever wonder why there’s no pink
in a rainbow? The answer is simple — there’s no pink light! There’s yellow and cyan light,
but no pink. That’s because red and blue are at opposite ends of the visible spectrum.
By going full circle on this and combining these two colors we actually include the enormity
of the entire electromagnetic spectrum into the visible one. Pink basically represents
everything in the universe that’s invisible to us. 5. Vantablack We all know that black makes us look sophisticated
and has the added bonus of slimming us down. But have you heard about the new black, Vantablack?
It’s like looking into a black hole! As strange as it sounds, it’s almost impossible
to see and we can only make it out because of its background. We see its edges but when
looking straight at it it’s as if you are looking at nothing. Not black, not something
very dark, nothing. It absorbs all but 0.035% of visible light — for comparison, dark
coal almost never gets below 0.5%. Vantablack was recently invented by English
scientists and is going to be used in designing stealth aircraft and advanced weaponry. But
its main use is in astronomy and space exploration, where sensitive telescopes need a very black
surface to be able to detect with great clarity and precision distant stars and galaxies.
We can see pictures of this material on the Internet because we’re looking through a
light emitting monitor, but the scale of darkness is nowhere near to the kind of utter void
that it truly is. 4. It’s My Red, Not Yours! If you and your friends are watching someone
in a red dress, were you aware that they might be seeing something totally different from
you? What you see as red your friends might see as what you know to be blue or green.
But all of you have come to know it as red, so you call it red! But how would you know?
What questions would you ask your friends to find out if all of you see the same thing?
Keep in mind that as you came to know your red, they came to know theirs in exactly the
same way! There are thousands of people who have different
types of colorblindness that prevent them from seeing red, green or blue light, and
we know that they see things differently from most of us. But what if we all see differently
from one another? Ultimately we’re all alone in our minds. We all have our different realities,
which may explain why one friend likes the red dress while the other thinks it’s hideous. 3. The Forbidden Colors By using red, yellow, green and blue in different
combinations we can describe all the other colors in the visible spectrum. Purple, for
example, can be described as reddish blue, lime as yellowish green, orange as reddish
yellow and turquoise as bluish green. But how do you call something reddish green? What’s
the name for bluish yellow? Don’t simply mix these two colors together like you’re
a four year old scribbling in a coloring book — imagine a color that’s part green and
part red, or one that’s both blue and yellow at the same time. Not having any luck? That’s because those
colors don’t theoretically exist, and thus are called forbidden. Everything comes down
to how we perceive color. The cones in our eyes detect red, green and blue at different
wavelengths. These wavelengths sometimes overlap. When green overlaps with red we usually see
it as yellow, but if the frequency is not that of yellow light then it’s either green
or red. It can’t, however, be both at the same time. The same principle applies for
both blue and yellow colors. This idea must have bugged Hewitt Crane and
Thomas Piantanida, because in 1983 they made the unimaginable possible! By doing a set
of experiments they managed to bring to life colors without a name. They created images
of red and green (and yellow and blue) stripes next to each other. By making sure that light
from each color only activated the same individual cones, over time the colors started blending
together to form something never seen before! Even though volunteers were aware they were
seeing totally different colors, they found it extremely hard to describe them. They were
essentially the first people to witness something new. 2. What Do Animals See? We’ve all heard that dogs are colorblind
and that bats are completely blind, but that’s not entirely true. Bats can see, just not
well, while dogs are only colorblind from our perspective. We have three color receptors, while dogs
have only two. They can’t see red. Would a squid that can only see in blue consider
a dog colorblind? Snakes can see very little “normal” color but can see in infrared,
while bees can see in blue, yellow and ultraviolet. Remember how infinitesimally small our visible
light spectrum is compared to what’s really out there? Just try to imagine a brand new
color — it’s impossible. Or imagine trying to explain to someone who’s been blind their
whole life what red looks like. You could say that it makes you feel warm and you associate
it with passion, but what would they really understand or imagine red to be? They could
know everything there is about light and color and it would still be as a foreign concept
to them. There just aren’t words that allow someone to grasp the true meaning of something
they haven’t experienced for themselves, which is known as an explanatory gap. For example, some butterflies have our three
color receptors and then an extra two: red, green, blue, ? and ?. We’d say just imagine
the possibilities, but the whole point is that you can’t. 1. Light Is Personal You’ve probably heard people say things
like “Oh, you have a beautiful purple aura!” or “You’re simply glowing!” It turns
out there might be some truth to that. Scientists from Kyoto University have discovered that
people actually emit visible light, but it’s 1000 times less powerful than what the naked
eye can see. They’ve also discovered that we reach maximum “aura” brightness at
about 4:00 pm because it’s a byproduct of our metabolism involving free radicals. The greater the distance between a light source
and an observer the dimmer the light is. That’s not because light gets lost on the way or
gets absorbed by different objects, but rather because the energy of the light is spread
out over a larger area of space. We see the sun equally as bright from all angles because
light travels in all directions in equal amounts. Over time and at greater distances light gets
more and more spread out until it becomes billions of single photons traveling in all
directions. Light also carries information. That’s how
we know where other stars and galaxies are, what they’re made of, if they’re coming
towards or moving away from us and what they were doing millions of years ago. The same
rules apply to our own personal light — it will travel in all directions through the
emptiness of space, possibly even going past the visible universe. It will never stop,
and it will carry a tiny part of you with it.

    great list..really made me have to concentrate and listen….love it.

  5. teenage spaceland says:

    @Virginia Bradley The "red, yellow, blue" primary color scale is pretty much just grade school oversimplification. The primary colors of light are red, green, and blue (RGB) and the primary colors of pigments are cyan, magenta, and yellow (CMYK).

    Months ago my sister and I were talking about what color she see's vs what colors I see. We both call it red, but her red could be my green sort of thing. Then as we were walking I saw a frog and was like hey a frog! she looked and then I said well it could be a frog to me but a cow to youand we both starting laughing

  14. Bill Clark says:

    Question: If I was out in space and not in a shadow any planet or other objects but close to the Sun or some other star, would I be able to see the other distant stars easily? Or would most of their light be muted out by the near by star/Sun?

    (I know during an Solar Eclipse some stars can been seen (and that some of them appear in different places due to the Sun's gravity)

  15. Mandy B says:

    Sorry to say you started out with a mistake. The prism splitting white light up had been known for ages. What Newton did was to isolate a single colour from the spectrum, put another prism in front of that and it showed the same colour. He disproved the prevailing belief that the colours could be recombined to white. Needless to say that the story is longer and the mathematical proof was a lot more complicated! He wrote a book called Optics. In Latin. Enjoy LOL 😀

  16. Alleycat 27 says:

    The presenter of this video should walk into a kindergarten art class. What will those 5-year-old children teach him? If you mix BLUE & YELLOW finger-paint you get green. Blue & green do NOT make yellow. Yellow appears when you REMOVE the blue from green! The primary colors are red, blue and YELLOW. SECONDARY colors are: Orange, Purple & Green.

  17. Barb Thornell says:

    Simon-I thought the primary colors were red, blue, and yellow (not green) and combining them made the secondary colors. Could you explain how that works a bit more please?

  18. Barb Thornell says:

    Er-thanks to Virginia B for at least n noting the difference via category. But I still don't understand WHY it would be different. Why we would see colors in the 2 categories differently…

  19. Sean Thomas says:

    Superb video! Quite thought provoking.
