Discuss Grout changing colours in the DIY Tiling Advice area at TilersForums.com

Have few small issues with grout. Using mapei ultra colour plus which is light grey when white but turns to a dirty brown when wet . It's in a wet area.
Is there any alternatives to keep the grout a light grey by using a sealer or is that a stupid question?
Or any other grouts out there someone knows of that hold there colour when wet?

Only epoxy grout does not change colour when wet as it is none absorbent, all cement based grouts are porous. A sealer may help but not like an epoxy and not permanent.
