Light itself is invisible.

its light that is the only visible thing and without it everything else is invisible

Not even one of those mad red cellophane ones you sometimes get in crackers that wriggle around in your hand?
I though everyone had had their fortune told by one of those (((poor xes)))

No,what kind of peasant crackers are they? We have gold watches and silver letter openers in ours

Back to the thread...

Light is the ONLY thing that IS visible to us. As eveything we see IS light (or light reflected,same thing) Just imagine what we'd see if we could see the whole spectrum,cos our visible light is just a tiny minute fraction of what there actually is. The Discovery channel put it like this. Ifyou got 20 or so miles of camera film,the visible light we perceive is just 1 tiny frame in the middle.

Transparent. It absorbs very little light. What colour is bog standard window glass?

Green, as you can see by looking at a pane of glass from the side.

Polar bears are mostly red, as you can see by looking at them from the fourth dimension (or peeling off their skin).
