Mosaic grout color: Can I change it after it's dry?
I made a tray by using glass tiles (that I cut) on wood. I first used white grout, but it was too light. So I made another batch of grout (weeks later) coloring it with some tea and red food coloring. I smeared it on top of the white grout and it came out too too red/pink!!!
What can I do to make it lighter? I even tried regrouting with the white but it just went back to pink!!
Should I paint it with acrylic paint? Bleach it? Any advise is greatly appreciated. The lovely tiles are mainly pink and they are disappearing within the pink grout!
HELP! Many thanks, Linda
