The condensor on the back, is black tubing. As
we know, black absorbs heat from the sun shine,
which makes the compressor work harder.

Of course, that condensor can be painted. Which
color paint is coolest in summer, and works best
to release the heat from the refrigerator? White, or
silver?


Whatever paint you use will insulate it so it works not-as-well. Lighter colors
will cut down radiation from the consensor, making it less efficient. Shading it
from the sun is the obvious solution.
