There are several ways to go about it depending on your code and preferences.

Assuming you have a background in the Screen already (Sprite or MovieClip or other Display Object):

1. You might want to change its color using ColorTransform class.

2. You can replace existing background with a new one (say, Sprite) and draw a rectangle of a desired fill color inside it using yourSprite .graphics class. In this case place a new background into the same stack order as your previous one - old one will be automatically replaced. Don't forget to mark the previous one for garbage collection.

3. You can draw a new rectangle inside the existing background, again, using drawing API (graphics class). Don't forget to invoke clear() method to delete previously drawn rectangle before you draw a new one.

Hope it helps.

or you use the color-matrix-filter.

with this you are able to change the color of pictures etc.
