A sequence of colors must be achieved that changes from frame 0 to 250, this will be constantly repeated. 1 and 250 will be different, yes, (and, as you said, each one of them) the ones that have to be the same are 0 and 250 and thus ensure that we start the same sequence again. Therefore, if there was a way to make that color sequence apply to all instances, when you start seeing the 2nd instance and restart the animation, we would see the 1st instance (which would be identical) and thus the jump would not be noticeable.
