I went to the same tattoo artist that did the quote on my right foot and also where I got my mallard done (different artist) Blue Flame in Raleigh.

With this color looks are deceiving to say the least. When it went on it was looking awesome:
I definitely wanted to grout to blend with the tile and not stand out. As it was drying and I saw it turn whiter and whiter. I went to Home Depot's app on my phone and pulled up the oyster gray color to see what it looks like online and it definitely looks different online than it does even on the bag. I turned back to Pinterest for solutions. Saw many pins about using grout colorant to renew or change grout color. My contractor said the gray was more of a green gray so I decided to go with what looks to be a green gray called natural gray colorant. And now I know to go by the online colors for a more realistic scheme after drying instead of looking at the bag color. (I assume the grout color would be similar but I'm only using it in the colorant so couldn't vouch for that.)
I did this right away, not want to live with the way it was looking. Also being a new floor I wanted to be able to show it off and I do not want to show the white lines. It was easy enough to apply. I did buy a fine brush at Home Depot but I ended up not even really using it. A toothbrush was the better option. I would basically just do a line at a time and put the colorant down and then quickly wiped away the excess on the tile and worked my way out of the room. One bottle was plenty for the whole room which is 100 sqft. So it was like a $15 fix and makes a world of difference.
