It will be a subtle FOC if that is what you are looking for. I prefer the jarring totally contrasting FOCs now myself. The ones where your eyes start to see things that aren't there cause your brain is having a hard time registering. My DVA/Bane's heart FOC does that.
Cool, I do want contrasting colors at the very least. I was also thinking about VA FOC with the SRD or an FO FOC
