Question

From the 1890s until the early 1930s, why were there very few movies in color produced?

Answer 1

It was a lot more difficult and expensive to produce them.

Answer 2

this was due to the fact that there wasn’t much inventory in having color contrast in lens for the filming industry. when they began to see that they could use a color sheet and see through a prisma they could see the colors reflect onto the screen as shown from the other end of the lens.
