That is to say what if everything and everyone in the entire world were all the same ONE color?
Skins eyes hair teeth clothes sky grass dirt autos food movies homes cars roads etcetera etcetera etcetera?
There would be no differentiation whatsoever. All one color all the time everywhere.
If we were born to it we'd know nothing else. That would be our "normal".
In the light of that what ONE COLOR would you want to see forever? For me? Gray blue with shiny silvery speckles. For thee?
