The tile grout is discolored after completion. It should be dark gray (charcoal gray from Kilto), but it shifts towards significantly lighter shades. See image.
I suspect I failed at this step (according to the instructions):
"Premature cleaning or too much water can cause discoloration of the grout. Regularly replace dirty cleaning water with clean water to achieve more even grout lines and minimize lime deposits."
The question is what can be done about this?

There is FUF joint color that works well. A bit tricky, you have to scrub a bit on the tiles, but it looks nice and good.
