No, they false colour the images of scanning electron microscopes
sometimes.

Based on what? State transitions of the electrons? Unless you're into quantum
chromodynamics, those are the only colors meaningful at that level. Right?

Alas, I could say everything I know about electron microscopes in a
140-character tweet.

No, physical areas, they colour different areas a different colour.
Helps separate things like insect body parts, etc.

Oh yes ... state transitions of the electrons. These are
different for different chemical elements, and some
microscopes can see that difference. You take three elements
and give each a color.

: Electron microscopes don't suffer from depth of field limitations.

Now that I know that, I may be over 140 characters.
