This is because dust particles become positively charged through photoelectric effects excited by solar ultraviolet radiation and X rays, so more intense direct sunlight increases the electrostatic forces that make the dust adhesive.
One leading theory is that ascending currents within the Great Red Spot dredge up material from deep down, and that trace compounds containing sulfur, phosphorus, and hydrocarbons turn red when exposed to solar ultraviolet radiation. White ovals also protrude above the cloud tops, so the fact that this storm is reddening might indicate a strengthening of activity.
