When my nephews were kids I used those old colorized movies from Turner Classics as partial proof that the old joke about the world being black, white, and shades of grey when I was kid was true. They grew up in the late 80's and early 90's watching TV shows including some great old stuff that Turner later colorized. I had told him how scientists had discovered how to improve the appearance of everything by adding other colors and as a result, scientists and artists and representatives from around the world met and collaborated on methods of colorizing everything that existed. Everyone agreed that blues would be great for the sky to lighten things up after storms; animals needed fur that blended into their environment so browns and tans like the dirt outside; rocks could be any color but earth tones (like their Mom was using in painting their house) got their names after everyone had picked colors for rocks, tree bark, leaves, etc. Plants would be green for the most part but leaves that had lightened or darkened in the fall could change colors too so every continent and country was able to decide how to color flowers and plants as they wished since coloring all flowers one color would just be boring. Snow and ice were white and water was up for grabs especially if it was in a river.

The notes they could read in the movie credits about it being a colorized version simply told them that all of the colors in that movie had been added later.

I was so convincing that one of them interrupted his teacher in class to let her know she was wrong about the rainbows and where color came from. I had made it clear that everything that we saw as colored had the colors that were assigned by international agreement after people had become tired enough of the BWG palette to sit down and make it all change.

In the end, the teacher told him he was wrong and he argued about it so I got a call one day that he had been in trouble at school and that the teacher was not thrilled to hear his explanation so I needed to clear things up for him since he was not inclined to believe her at all. I'm not sure that I ever got that completely cleared up because, to me, it was just too funny that I was the most trusted source.
