    Sure you didn't do that yourself? You can "change color" of a folder under the "More" menu.

From what I can see, the only automatic thing Google does to folders is add a person icon to folders that have been shared.

You can change the color of a folder yourself, either by right-clicking on it or checking the box and using the "More" menu.

folder context menu with "change color" option

The most likely explanation is that you changed the color of those folder in the dim-and-distant past and it simply slipped your mind.
