Tiling

Blotchy colour of new grouting

Had our bathroom tiled and the Mapei coloured grout has dried quite blotch in some areas. The colour is jasmine but it is not uniform, some looks the correct colour, some look paler and some look darker. Is there any remedial work other than grind out the problem areas and regrout? What caused this to happen in the first place? If we do have to regrout some areas could we cause a different problem if the mix isn't exactly the same powder to water ratio as the original, and end up with a slightly different shade? Thanks for any guidance anyone can offer. Carol
