Yes you are supposed to seal your porus tile before grouting. I can't see a way to even the colors unless you darken everything. I've done that with wood stain with greater and lesser success. There must be a "color" that is added to grout that might be applied directly (more or less).<p>Muratic acid is used to clean cement "over spray" and grout mistakes ... but what it will do with colored grout on a porus surface, I don't know.<p>Good luck.
