Designing Kitchens and Bathrooms - Changing the color of tile grout

I redid my bathroom a while back with white 3x6 ceramic tile with white sanded grout. I was very happy with it and so is my wife. Even though I had the feeling that I should have added an accent strip in the shower area. This was proven when a home assessor came while we were looking into refinancing. He mistook the tile for simulated tile paneling. I was very wounded by this, and have been wondering about the possibility of changing the grout color.
Has anyone ever even heard of such a product or procedure?
I wanted to go with a beige or light brown to begin with, but I knew that I have limited experience with fitting tile. So I chickened out and used white to be safe. Now I'm kinda sorry!
Have a good day.:)

If you have a light grout and wish to go darker, there are products that you can use,,,I'll try to find the old thread, but it may be tommorrow, Do a search for grout stain..see what you find.

Oops that was easy. Thank you for the reply Gunguy45. I suppose I should have began with that. The very searchable term "grout stain" didn't even occur to me.

This is the old thread I was talking about. The poster had good results it seems...

Yep, that answers all of my questions and gives me an idea of how much time this will take and what results to expect.

I think I will let my niece do it since she likes to color all over the walls anyway.:thinker: It's perfect!
