Coloring your Grout

I've often grouted with multiple colors before, to make areas of a mosaic stand out. In a recent class, one of my students said she colored her grout with water color. She piqued my curiosity and I decided to try acrylics mixed with water on a mosaic that I wanted to have more contrast. This one is simply called, "San Carlos, MX Landscape," taken from a photo (with permission) by ​Leonel Garza Sanchez. Hold your mouse over each image to read what I am doing in the picture.

After the painting is the cleaning...

First round of paint leads to more...

Final comparison...I like the mosaic but next time, I would use smaller tesserae and more yellows. There's always a next time, mosaic artists, so don't be afraid to try something new!
