Changing an active object a different color

[FormerTGFGuy]

I want to make a character in my game flash red when hit by an enemy. Is there an easy way to do this? There's no way to do it with effects, because none of the options allow for a solid color like that. And it's far too slow to replace the character's RGB locations with red for a few frames and then back to his regular colors.

Looki made a Simple Mask coloring shader that should be up for the task.

I installed this, but it keeps saying Depth.fx is missing, even though it's actually there. What am I doing wrong? I even tried copying Depth.fx to every possible MMF2 folder (not just extensions) and it still gives me the error...could it have anything to do with the fact I'm running MMF2 from Dropbox rather than my hard drive?
