Without knowing what "good results" are to you or what a "vibrating effect" means to you, we can't be any help getting you there. White is not a color spectrum.
Taking a random guess at what you want, if I had an image with white in it and I wanted it to randomly cycle through colors I would use the "change color" effect. I'd set it to match white and filter it so it grabbed only my white object. Then I would reduce transform lightness to -50, transform saturation to 100 and put an expression on the transform hue with something like wiggle(1.2,180).
