In the video of Dr. No, I thought that the titles are following the sound wave and the colors changed due to how high or low it goes. The colors make a motion and not only that but that even if it’s not the title it would help place the text in a certain spot.

For the apple video the colors are from the rainbow set when it first starts up as the fill for the apple. The colors then play their own roles to join together and create the objects. The dancing silhouette would look transparent that the color would combine and create a 3 color in between.
