Grey Spots in Countertop

Hi there. Just poured my first countertop yesterday and we are quite pleased with the results. There are a few grey spots that have shown up after drying - I assume where the concrete got a little wet after pouring, which seems to have washed out the gunmetal colouring we used in the mix. Is there an easy fix for this to make the colour all uniform (stain, or a slurry with the gunmetal colouring?). Thanks in advance for any help offered!
