Appropriate balloon color for anniversary?

It's my anniversary tomorrow. My wife has just gone to sleep and she's snoring SO LOUD. I bought ear plugs and have been wearing them, but they are not enough. I found a device that will work, it's a bit like a foam plug for her mouth. I think I'm going to wait until midnight and then jam it into her gaping maw until no air can enter or escape. My question is, what color balloons should I blow up to celebrate a good night's sleep?
