Why does this otherwise excellent series always depict electrons as red and protons as blue when everybody knows it’s the other way round?

If you have ever looked at an old transmission electron microscope with a viewing screen, you know electrons are green ; )

I thought everyone knew that neutrons are blue and electrons are yellow.

I refuse to believe neutrons can be any color other than white.

Electrons are blue and oxygen is red. Don't be ridiculous.
