"Cream" can be a very difficult colour to get right! Some are too yellowish, others can be either too cool, or some have pink undertones (such as the dreaded Magnolia)
After a lot of trial and error, Dulux Ivory seems to work well, we have used the "Easy Care" finish, which is pretty tough and any marks wipe off.
If you are looking for more of a colour, but still want something fairly neutral, then "Crispy Crumble"(Dulux again) has worked well in our South facing sitting room. It actually looks like a sort of grey/green.
Colours will look different in different lights, a colour I loved in a friends house, which looked like a soft grey, when I tried a tester in the room I was decorating seemed to be an ice blue!
