How does the pink dye work on various skin tones and colors?
Obviously, the lighter the skins tone the brighter the dyes stain. The dye will absorb into porous material and will transfer to any object, solid or porous, it contacts. This feature produces an abnormal coloring effect that is intended to raise suspicion. Spraying onto the primary facial target area of the eyes, nose and mouth will cause painful irritating and lachrymatory effects as well. The combination of these features is intended to produce an unexpected and complicated set of circumstances to hinder an assailant; creating an opportunity to escape. The visible pink dye marking of a perpetrator should increase their inability to evade detection and deny involvement in foul play, and increase the rate of capture and conviction.
