Faded stain

Hi all. We have a ~7 year old patio around the pool. I do not know how the original Terre cotta color was made. But it has been sealed with b&j wet look clear. Over time the color has faded. I am ready to re-clear (2 years old) and was hoping you all may have some suggestions on how to bring back some of the vibrancy. I am mostly diy. But happy to spend on good product. Thanks!
