ULTRAMARINE!

青色！

But how exactly do we get to see these amazing colors?

但我們是如何能夠看到這些令人驚嘆的顏色呢？

Well all color begins with light. So as the sun beams down overhead, it's actually casting

嗯，所有的顏色都是透過光線而來的。所以當陽光從你頭頂上照射下來

the entire spectrum of colors over you. When that light hits an object - like an apple

它事實上是將完整的光譜投射下來。當陽光照射到一個物體 - 像是蘋果

- the object absorbs some and reflects the rest. Whatever wavelengths of light are reflected

- 這物體會吸收一部分光線並且反射剩餘的光線。而某些特定波長的光線被反射後

back are the colors you see.

你就看到那些波長所代表的顏色

So that ripe apple has a wavelength of about 650 nanometers, which is science talk for

所以，一顆成熟的蘋果反射的光線波長約在650nm，這就是科學家所說的

the color red.

紅色

That amazing kaleidoscope of colors gets seen by your eye through three different types

你的眼睛看到令人驚艷的萬花筒的顏色

of color receptors: red, green and blue (if you didn't know, that’s RGB. now you know).

是經由眼睛內三種不同的感色受體:紅，綠和藍 (如果你還是不清楚，就是RGB囉。現在知道了吧)

Theses are found in cells called cones in the back of your your eye. They are responsible

你眼睛後方有很多稱做視錐細胞的細胞。它們負責

for photopic or daytime vision and see the full spectrum of colors that can be made from

在白天調適你眼睛的感光，並且它們可以看到所有由紅綠藍顏色

these three colors.

組成的光譜

There are also rods in your retina that allow you to see, but they are responsible for scotopic

在你視網膜上也有視桿細胞，它們也是負責你的視覺，只是它們是負責

or night vision.

光線昏暗時或是夜間的視覺

So humans have three color receptors that allow us to see the rainbow, but what if I

所以人類擁有的這三種顏色受體能夠讓我們看到彩虹

told you there are animals that have more than three?

但如果我跟你說，有些動物擁有不只三種呢？

Well the mighty mantis shrimp has an incredible twelve different photoreceptors in its eye.

嗯，看看威武的蝦蛄，牠們眼中擁有高達十二種不同的顏色受體

That’s four times more than us! This tiny creature can see a vast array of colors that

是我們的四倍之多！這小小的生物能夠看到更多我們眼睛不可能看到的

are impossible for us to ever see. It’s probably like looking at a quadruple, super

多種顏色。這大概是一次能看到一個四倍

mega rainbow all the time. Wowza****

超巨大的彩虹。哇！

Want to know more about what happens to our eyes? I think you’d love this explanation

想知道更多有關你眼睛的奧妙嗎？我想你一定想知道

why we get those sagging, tired bags under our eyes.

為什麼我們會有這些鬆弛、疲勞的眼袋於我們眼睛下吧！
