SATURATION
This shows the trajectories of some blobs of colour as they egress from three moving bodies. Each body and all the blobs of colour that egress from it accelerate towards one of the other bodies with a constant magnitude of acceleration: the yellow blobs and the body that expels them accelerate towards the body that expels magenta blobs, the aquamarine blobs and the body that expels them accelerate towards the body that expels yellow blobs and the magenta blobs and the body that expels them accelerate towards the body that expels aquamarine blobs.
Over the course of its life, each blob loses brightness. If it passes close to a body other than the one that expelled it, it also loses saturation. Continue reading
