when i was married, i always chose the colour scheme [paint and fabrics] and my husband got on with it.
and, i suppose, it's the same when my guy gets involved with decorating [he did my whole house a few years ago] - i buy what i want and he paints the walls/ceilings/woodwork with my choice. i also get to choose carpets, furniture, furnishings, etc, etc.
i used to do the decorating myself before i met him and, i must say, he objected in very strong terms to the pink in the bathroom and loo!! i think that was the first thing which was replaced - and he refuses to use pink paint again!!!
almost got my house as i want it - and i see no point in decorating every room in the same colour with the same carpet on the floors - i like a different "theme" for every room.
