Stone Paving Slab Lightened my Oxalic Acid

Hi
First post on this forum
I used a mild soln of oxalic acid and water to remove some really bad rust stains on a sawn wood fence due to non galvanised nails being use..this has worked a treat so many thanks to the forumn for this.
In the process I knocked the soln over onto a flag....doh.....I didnt realise for 5 mins and when I did washing it off and scrubbed it wtih washing liquid.
It now looks markedly lighted than the rest of the patio which is pretty large and I'd prefer to lighten the whole patio flag area.
Any idea how I can darken the flag and surrounding area to blend in more with the current paving
Thanks
Martyn
