Can we change the color of paint pigment electrically or otherwise? Imagine a solid color object, say its painted grey to simulate a desaturated color. Can we change that grey color to a vibrant other color? Maybe a coating that has to be applied to the paint surface? I have seen cars painted with designs that glow but can we change the color of the pigment, or simulate it? Imagine having a car that has interchangeable paint colors or variable images that can be rendered in the paint?. I tried searching online but didn't get any real results. Electric Paint video looks interesting, a conductive paint.
