This set of actions are some extensions I built trying to mimic Cross-Processed color FX and some harsh color effects I saw becoming popular. (Strong magenta hues while leaving the skin tones semi natural)

Many of these extensions have a “single click” play and a dialog mode for fine tuning the effects.
Should work with Photoshop CS (and possibly PS 6).
