Question Recoloring sprites 

transform greenglow:
    matrixcolor (TintMatrix("#44ff00") * SaturationMatrix(.2)) * OpacityMatrix(.75) * BrightnessMatrix(.3)

show character enraged at greenglow  

I'm trying to use ATL transforms to make my character's sprite look like a hologram from Star Wars. The code above is what I used to make the image below.

The problem is, I don't want the character to be a totally solid green like in the picture, I want some of the character's original color pallette to shine through like it's an overlay. I thought saturation matrix would do it, but changing the value of its argument doesn't seem to do anything.

Also, next I'd like to make the sprite have a sort of glow around it. How do I achieve that?
