Fun,
but Calvin & Hobbes did this 20 yrs ago. Calvin asked his Dad why old photos were B&W, and his Dad explained that the world was B&W until new technologies were invented after WWI .

I was going to remark on the same thing. That was funny. But you remember it just a little off. When Calvin asked why photos were B&W, his dad said the world was B&W, then changed to color. When asked why the photos didn't change to color as well, he remarked that they were COLOR photos of a B&W world. When asked why old paintings then were colored, he remarked that everyone knew those old painters were crazy.
