Colour modulation questions

[Macaw]

Question 1: I am wondering how its possible to modulate the colour of a object as a loop? For example, imagine a big solid red background graphic that changes between a bright orange then back to red, which could give an illusion of a fire or battle happening in the far distance of the background in a side scrolling game.

Question 2: Is it possible to change everything in a frame to a monochrome colour? I know there is a monochrome 'effect' that can be put on active objects but thats about it.


Thanks

1. The easiest non-technical way would be to have 2 objects, one orange and one red, place on top of each other. Have one of them constantly fade in and out.
2. You can apply effects to layers. Layer effects apply to all objects on the layer.
