Hiya - I am putting cream tiles down in my kitchen and am having a bit of a dilema about what colour of grout to use. The shop had the tiles on display with ivory grout and it looked really nice so i bought it - but have been told by several people that I would be mad to use it because it supposedly goes a peachy colour when you use detergent on it and that grey would be better. Has anyone else had this problem? if so which would you recommend?
