When is 'cream' too white?

Is this white or cream?

Honestly, I sometimes wish my parents tell me what proper modern Chinese wedding etiquette is. It's not really something I bother Googling, because I assume that my parents are okay with my overwhelmingly westernized upbringing and rules. And then, lo and behold, they, at last minute (or sometimes even much, much later), tell me that something is a faux pas. Take flowers for example. I'm apparently not allowed to have white flowers, because that's what's used in Chinese funerals (but a white dress is allowed. In fact, a western wedding gown is EXPECTED. And mine is white-white. Not cream. Not off-white. Not champagne. The cake frosting is expected to be white, also.) Fine. Let's go with cream. However, when does white become cream? Is the picture above cream or white? My bridesmaids are supposed to be the opposite of me - purple dresses with a predominantly cream bouquet (even if white were "allowed," it would be too harsh for their purple, anyway), while I have a predominantly purple bouquet. I don't want to ruin my colour scheme and don't want the "cream" flowers to be too-too yellow/peach, either.

Any suggestions?
