If the colour is ok when wet then it's because the drive needs to be resealed.
Resin has the same ligfht refractive properties as water. So it will be ok when resealed
You probably washed the resin of the surface, this happens when the surface resin wears away with traffic movement either foot or cars resulting in white patches If these white patches can't be seen when it's wet then as I said resealing will cure it
