Thats kind of apples and oranges really. I like the bold curtain but it's difficult to see how it works with your space in general.

So cute.......................well you can always use white, but I've seen grey and white drapery panels at HomeGoods that would be more interesting.

Than go with what you like!

I just noticed on second pic that walls are grey, white will stand out:)

I vote white, seems to look great with revere pewter and dark sofa
