Okay, here are your layers from bottom up:


1. (Lowest): The normal background. Let's say it has brown earth and a blue 

sky.

2. A pink man and some green trees, all of them symbols.

3. Solid green layer.

4. An exact copy of layer 2, but use color effect to change the man to 

purple and the trees to orange.

5. A mask layer in which the mask moves around.


Now set the layer properties of 3 and 4 to "masked." Wherever the mask is, 

layers 3 and 4 will show through. Since layer 4's objects are directly 

above layer 2's objects, when layer 4's objects are revealed by the mask, 

you won't see the layer 2 objects under the mask. So it will look as if the 

layer 2 objects are changing color, just under the area of the mask.


Remember, a mask in Flash reveals what is underneath it in the masked layer(s).
