Or, if you prefer, we could go more Sin City, and do the same thing with cel shading turned on, like this.
Of course, it's not just clothing that will stand out - you could do the same with blood splatters, a red car, or anything else. We're aiming to add some options so that you could have green or blue stand out, but no promises on that. Any colour other than the three primaries is pretty much out of the question though.
Usual disclaimers apply: this is really early dev code, not representative of final quality, and we don't have a release date for it.
