Most common cause of that is a bad video connection. Sometimes, the silver plated connecting cables just tarnish. Try exercising it (sliding it in and out of the connector on the TV and the source) and see if that doesn't solve your problems.
with a few seconds' thought, I have the following list: Color information is not being broadcast Color information is being corrupted in the transmission chain Signal quality is poor to the point where color information cannot be decoded The color decoding section of the receiver is faulty Two of three component cables are faulty In other words, the problem could be anywhere. To provide an answer that has any chance of diagnosing the problem, much more information about the television, the incoming signal, the receiver, the type of signal interface is required.
I think it froze. If it still works, check the computer settings and if that is fine, and one is available, try another monitor. It could be an issue with the computer monitor.
You have no cable connection.. or TV service.. or a wire's loose.
Read a book!
It was broadcast in Color although if you still had a black and white TV in 1966 to 1968, it was of course in black and white.
Black and white are colors, but technically both can be the absence of color, or the total combination of colors. B&W television used shades of gray (although that might also qualify as a color). The term "color TV" means a "full spectrum of colors" rather than simply grays.
Neither black or white are actually colours. They aren't primary colours and you can't mix other colours to make them. So it's just a black and white TV. It becomes a colour TV when it, um, has colours.
black and white
You couldn't! The first bit of the film was done when there was only black and white tv and the second when color came out.

Black is not a color it is the absents of light so different shades of the white would give you grays.
Black and white television were broadcast in this manner due to that fact that television sets could not display color versions. By the mid 1970s most television sets were color models and therefore black and white shows were discontinued.
1972
because TV could not be made in color that is why
Black And White! The word means "one color".
