Red light, green light.

Red light... green light.

When there's a lot of chlorophyil around, they see a lot of green light.

That light is green.

Color of planet trails

It's a red light!

A beam of white light is split by a prism into rays of various colors.

Garden of Coloured Lights

And speaking in terms of light, pink should probably be called minus green , because pink is what's left over from white light when you take out the green.

It's a red light!

Fade trails to background color

I saw it. Yellow light's for my eyes only.

The railroad worm, Phrixothrix hirtus, can light up its body in two colors red and green.

The color for solar system object trails.

If checked, the color of the planet trail will be blended into the background sky color.

Fade trail color into the background?

It's very technological, it's very complex, a little daunting.

What is that? A reaction test?

Well, the sun emits all colors of light, so light of all colors is hitting your pencil.

So, what if you had a yellow pencil sitting on your desk?

Light is resolved by a prism into seven colors.

Is it something about the details or the colors?

Maybe not surprisingly, in the deep ocean, where it's mostly blue, the photoreceptors tend to see blue light.

Fade planet trails to background color?

There's simply no pink light.

No. No, Susan, you're, like, really glowing. You're green!

And you'll see that it leads with a shifting star field, and there's an Aurora Borealis in the background, kind of morphing with color.

Consumers don't really like these light bulbs.

But one of the most popular ones involves green fluorescent protein.

It's not there.

The cones, however, are a different story.

I want to think.

Now you can see that changes the light that's coming through there, right?

In 2008, the Nobel Prize in Chemistry was awarded for work done on a molecule called green fluorescent protein that was isolated from the bioluminescent chemistry of a jellyfish, and it's been equated to the invention of the microscope, in terms of the impact that it has had on cell biology and genetic engineering.

And so the material can assume a lot of formats.

The lowest frequency light that we can see is red and the highest frequency is purple.

Look down that infinite reflection, and it will get dimmer, because some light is lost or absorbed every time, but it will also become greener, because green light, that is light of a wavelength that we perceive as green, is best reflected by most mirrors.

As you can see there are three icons at the bottom.

What you're seeing when you put it through a prism is that you heat hydrogen up and it doesn't just glow

Okay, now, honey, imagine the organs in your body floating in the different colors I project on you, okay?

The sound of the waves and other environmental sounds that you can hear in the space are translated into data and visualized as light.

So, how come this region, where the red and green lights mix,

This is cultures, identical cultures, of cervical cancer cells.

Rendering can get even simpler than this.

And whenever they made one of the two choices, chose one odor, in this case the blue one over the orange one, we switched on the lights.
