I recently renovated my bathroom using rectified tiles. Being conscious of the extra effort required to get sufficient grout into the narrow spacing between tiles so that I didn't merely bridge the gap and have it fall out later as seen sometimes - even in shop displays, I worked the grout into the joint well. The only problem was that using a black rubber grout applicator the sharp rectified edges of the tile wore minute particles of rubber off the applicator and discoloured the grout slightly. Where this was obvious as I grouted I removed the contaminated grout and re-did. After everything dried I noticed there were a few areas of very light discolouration - the colour of damp grout. Today I finally got around to trying to scrape out enough to reapply a thin top layer of new grout, however much harder than expected. I can persevere (about 2m), but time consuming as I have to be careful not to damage the edge of the tile, particularly at corners, or veer off the grout onto the tile and leave a metallic scratch - which has happened already. A bamboo skewer juts doesn't cut it!
I was thinking that a grout pen may be an easier solution but as I have never used one I have no idea of the end look - may look artificial or more noticeably that the current look.
Is a white grout pen a good match for ultra white grout? How will it look on a wall with unpainted grout?
Will it be the pen or hard labour
