How to Adjust Movie Symbol, Text or Button Color Using the Flash Adjust Color Filter
Adjusting the color of a button, movie or text object over time is simple with the Adjust Color Filter.
The filter is applied at frame one, then copied to a second frame where it is altered. A tween is added and the color changes over time.
Add a rectangular object to the workspace with the Rectangle tool (r key).
Select the rectangle and convert it to a Movie Symbol (Modify > Convert to Symbol (F8)).
With the rectangle Movie Symbol still selected, open the Filters panel by clicking the Filters tab (Window > Properties > Filters).
Add a filter to the Filter panel by clicking the plus (+) icon and selecting Adjust Color from the pull-down menu.
Move the sliders to adjust the color.
