Loriann, Just a suggestion, but four years ago I had a Kott Koatings man out who re-did my HARVEST GOLD bathtub and tile surround to a more neutral and workable WHITE. It still looks terrific and I understand that now they can even add color designs like flowers and stencils to re-done porcelain. Hope this helps...now if anyone knows how to paint the grout on floor tile, I'd like to hear from them!
You can recolor the grout on your tile floor, but not the way you might think. It involves alot of elbow grease. Buy yourself a tool called a grout saw, which is used to remove old grout from between tiles. Once you have removed the grout, you can regrout the floor with any precolored grout the you desire.
