When I did the (simple) interpolation work on [Point2D/3D](https://bugs.openjdk.org/browse/JDK-8226454) I also looked at `Border` and `Background` because animating the color of these is rather common. The problem is that they are rather complex and don't interpolate trivially as a whole. As a user, if I want to interpolate between images, I would think of a smooth transition between them, not a jump cut. There are other oddities as well. ------------- PR Comment: https://git.openjdk.org/jfx/pull/1471#issuecomment-2151084870
