If there is no light (infinitely without light) what colour is something ?

Black.

Does air have a smell?

If a tree falls in the forest and there is no one alive on Earth, does it make a sound?

Agree. With no light there is no color. Color is a result of wavelength-selective light reflection or absorbtion.

Is an apple still red when you turn out the light? Kind of.

I like the other version of this -
If a man does something not quite correct and there's no woman around, is it still wrong?

 

It's gonna depend on how you define light and color. Many other life forms can see and sense many more red colors and many more violet colors than we can.

And many objects can reflect or emit colors that can't be seen. So it looks black to us.

The tree falling always makes a sound.

And I believe I heard where they found that mice can smell oxygen.

Chartreuse?

 

Depends upon you definition of color I suppose.
I would say that an object has an intrinsic color (the wavelength, or group of wavelengths, of light it reflects) regardless of whether it's illuminated or not.
It doesn't lose that just because it's in the dark.
But to determine that color you need to illuminate it with white light.

 

It's like, Is "color" spelt wrong if there is nobody around to read the word? These are all illogical questions because the meaning is based on someone being there experiencing them.

 

No, it still exists but nobody is looking at it. Simple as that. To go deeper into it I suppose you have to think about defining the word "exists"

 

What color is a red quark?

Prove it.

Depends on what the definition of is is!

 

Things don't have color. They reflect or emit color. Reflected color is color the thing doesn't want.

A red thing takes all the colors except red.....it throws red away.......that's why you can see red. It keeps the other colors. You can't see the colors a thing keeps.....only what it throws away.

Emitted color will depend on the thing......and the temperature.
