Because that's how physics works.
They're colorful for, to a first approximation, the same reason a neon sign is colorful: the energy being emitted is limited to a specific value, and the wavelength corresponding to that energy happens to lie in the human visual band. Since it's only one wavelength rather than a broad spectrum, we perceive it as a specific color.
The reason there are different colors is that different transitions are taking place, and each of them has a particular energy (and therefore wavelength of light) associated with it.

What is the northern lights official name?
The official name for the northern lights is Aurora Borealis in the Northern Hemisphere. It is caused by solar particles interacting with the Earth's atmosphere, resulting in colorful light displays.
Do capitalized northern lights?
Yes it's name\place sort of
Do the northern lights emit a sound?
No, the northern lights do not emit a sound. The light phenomenon is a result of charged particles from the sun colliding with gases in Earth's atmosphere, producing beautiful colorful light displays but no sound.
What causes the northan lights?
The Northern Lights, also known as auroras, are created when charged particles from the sun interact with Earth's magnetic field. These particles collide with gases in the Earth's atmosphere, producing colorful light displays in the northern hemisphere.
Difference in Northern Lights and Southern Lights?
They are the same. They simply occur in different hemispheres. The southern lights are less well known because there is less inhabited land around the south pole, where you would see the southern lights
What is a colorful light display that is in the polar night sky?
the northern lights.
What is the term for the often colorful lights that occur in the atmosphere above the earths norhtern geomagnetic pole?
The term for the colorful lights that occur in the atmosphere above the earth's northern geomagnetic pole is called the Aurora Borealis or Northern Lights. These lights are a natural phenomenon caused by the interaction between the solar wind and Earth's magnetic field.

What does the term "borealis" mean in relation to natural phenomena?
The term "borealis" refers to the Northern Lights, a natural phenomenon where colorful lights appear in the sky near the North Pole.
What causes the mesmerizing natural phenomenon known as the aurora borealis or northern lights?
The aurora borealis, or northern lights, is caused by solar wind particles interacting with Earth's magnetic field and atmosphere, creating colorful light displays in the sky.
How is the phenomenon of the Northern Lights created?
The Northern Lights, also known as auroras, are created when charged particles from the sun collide with gases in Earth's atmosphere. This collision produces colorful light displays in the sky, typically near the Earth's magnetic poles.
Aurora borealis is a name for what natural phenomenon?
The aurora borealis night-sky displays are also known as the northern lights, or the northern polar lights.(or the southern (polar) lights, depending on where you live)In the Southern Hemisphere this phenomenon is also known as the aurora australis.
What causes the northan lights?

What creates the phenomenon known as the northern lights?
The northern lights, also known as auroras, are created by charged particles from the sun interacting with the Earth's magnetic field. This interaction causes the particles to emit light, creating the beautiful and colorful light displays in the sky.
