How to Animate Flash Object Color
A Tint Tween uses a Motion Tween to change a symbol's tint over time. You could start with a green object, set the first keyframe to gray and the last keyframe to blue and your object would fade from gray to blue. The green color would never appear.
For more information on Motion Tweens, see topic, Motion Tween.
Add an oval shape to the stage using the Oval tool (o key).
With the oval shape selected, convert it to a Movie Symbol (F8)(Modify > Convert to Symbol).
Click frame 20 of and press F6 (Insert > Timeline > Keyframe).
Right-click the timeline between your keyframes and choose Create Motion Tween from the pull-down menu.
Click the keyframe at frame one, then click the oval object.
Open the Properties panel (Cmd/F3 (PC-Ctrl/F3))and select Tint from the Color menu.
Click the color swatch and pick a shade of gray.
