Replying to @lmk@infosec.exchange
@lmk@infosec.exchange That's like asking what color is a prism? It's what it is reflecting or transporting, which in general is all the colors our eyes really don't see. You can't see something if the color or photon is absorbed. We see what bounces off.

Science fact of the day: Every colored thing we see is the opposite of the color we are seeing. You only see color that the object doesn't absorb and reflects back instead. That red object. It's really every color but red. Now go live with that realization.
