Wedding color question.?

I am getting married April 7th 2012 and am just starting to plan! I can’t figure out which wedding colors would look best in April in Ohio. I love yellow and gray like this http://stephaniewilliamsphotography.com/blog/wp-content/uploads/jessica_59.jpg but we both love orange like this http://www.hollye.net/vandk17.jpg but i’m worried it might look too fall-ish. We are getting married in a building in the city with a loft feel to it. It has brick walls and huge floor to ceiling windows with green trim. Do people usually pick colors based off the venue? Or does it not matter…Suggestions?
