Coloring tufa after the fact

Hi, I just finished a 300 foot long garden wall & since we had such a long wall, we had to do it in sections with multipl batches. We used a measured amount of powdered cement colorant in each batch of tufa, however one of the sections looks grey compared to the rest of the wall. I don't know what happened to that section. We tried to dissolve some of the powderd colorant in water & sponge it on, but it dried to a powder & came off. How would I go about coloring the finished wall? I am mainly concerned about the one section, but I figure I will have to do the entire wall to make it look consistent. Thanks.
