Benefit Hello Flawless foundation shade ridiculously inaccurate

I have heard such great things from Benefit Cosmetics, so I decided to spoil myself and order online since not many places stock it. I ordered the Hello Flawless in Ivory (I am pale and this is my standard shade across all brands) Imagine my surprise when it came and the "Ivory" is literally 2 or 3 shades darker then Ivory in competitors brands. I am very disappointed and it is not like Benefit is a cheap brand. My sister is very tanned and dark and it matches her skin. Quite sad about this, thought i had made a good purchase, don't market something as Ivory when it's clearly not.
