The 4th one and the red and black is good, but I would recommend to like remove the green you have on and maybe like replace it with white? Or just go with whatever you think is best.
The first (original) and third ones are the most well executed since they have the most natural-looking colour schemes (the other ones seem to have random colours in some areas). Utlimately the third one is probably the most visually appealing since the dark purple and light green produce a pleasant contrast.
