What is the smallest object that has a colour?

I have a ring that has all different types/colours of precious stones in it. Honestly, the tanzanite stone is the smallest coloured thing you’ve ever seen in your life.

I saw an article with a picture once where you could see the light they were causing to be emitted from a single atom. I forget what element it was.

Nanoparticles! They emit in cool colors, with red at the smaller side of the spectrum and diameter.
