How would you make this code more efficient?

How would you make this code more efficient? or does it have to be this much code for a simple rollover turn brown, rollout turn back to white?
I'm very new to AS3.

// home text is text displayed on the Stage given a name.
// home_btn, blog_btn, greenBtn, and blackBtn are buttons on the Stage.

// Get access to the ColorTransform instance associated with home text.

var bioButtonText:ColorTransform = bio_mc.transform.colorTransform;
var pressButtonText:ColorTransform = press_mc.transform.colorTransform;

// This function is called when home_btn is rolled over.
// apply the change to the display object
// Set the color of the ColorTransform object.
