The grout color change could come from where someone use an acid
based cleaner too strong in one area. Or as Fred stated it could be in the mixing.
To fix I would recommend a good clean then Color Seal the grout
lines.

would be causing the grout lines to have two different colors? . Is it due to
that the grout lines where colored sealed in the past?
