Hi everyone,
I’m looking for advice on whether it’s possible to restore the color of some charcoal decko composite tiles on our back patio that have started to fade over time. I've noticed that when the tiles get wet, they appear much richer and darker. Would it be feasible to paint them using acrylic paint to restore their original color or replicate this look ?

I’ve attached an image showing the tiles in their normal state and after getting wet to illustrate the color contrast. Any feedback or suggestions on products would be greatly appreciated.
Thank you !
