The entire world was only black & white until 1960 or so...Kodak had experimented with it as early as the late '30s & early '40s, but it was too new a concept to be popularly accepted and most people could not see it. It was Zenith, I think, who introduced color to the masses. Or maybe Polaroid in '58 or so with still photos. But until then, everything was "colorized" by women with paintbrushes, using their imagination. We have become so used to it, we take it for granted now and automatically see things in 'color'. But we owe a lot to those women, figuring out what 'colors' things should be--if it were not for them, if it were up to a bunch of men, god can you imagine how things would look now??
Sky King & Penny would have been flying a purple Beechcraft across a yellow sky, Lloyd bridges in 'Seahunt' would have been diving in a red ocean, and Howdy Doody would have been wearing red & green plaid shirt (...Oh wait--he was, wasn't he? Well he was a guy......)
The 'color conspiracy' really took off in the early '60s, around the time they removed the tube testing machines from the grocery stores. That way, the men like my Dad lost one more place to hang around and talk man-talk about things and the women with their 'color' could further their takeover of the world....."Mauve" and "puce" did not exist until the late '80s, the wimmin have to keep coming up with more colors to keep us off balance & guessing. That's why men today yet still don't know what those are: they have not been imprinted onto our brains as existing yet.
There are more colors on the way, it is a vast conspiracy. Don't believe me? Look it up!
