Change color of tab icon

I am building an iOS 7 app using SDK 3.22 and Studio 3.2 on a MAC running OS 10.9 testing on a device. I want to change the default gray tab icon color to white. I have figured out how to change color when it is active but not inactive. Here is my tabGroup:

var tabGroup = Ti.UI.createTabGroup({
        tabsBackgroundColor : '#EEB111',
        activeTabIconTint : '#C8960D',
        top : theTop
    });
