What colour curtains with neutral colours??

I know you have all probably answered this question a million times....but I would like to know what colour curtains (and accents) to put in my living room to brighten the room. The walls are a medium taupe, the couches brown leather, an accent wall in a sage green, carpet is a lighter beige and the window has brown venetians on them. The coffee table and end table are gl with a steel grey bottom. Everything is so drab in there I need something to brighten it up!! I don't really like oranges or mauves or light blues....so I was thinking about white. Do you think this would work?
