Scripting Guidance

[Mykel]

Okay, so I've recently taken up an interest in scripting. So far all I am doing is looking at scripts and trying to understand them, and then editing them in some other way to try new things. I could use your help some. If someone could please explain the following script in the most basic of terms possible, it'd be greatly appreciated.

NPC Code:

---

if (playerchats && strequals(#a,Mykel)) {

  if (startswith(/skin,#c)) {

    setcharprop #C0,#T(#e(6,-1,#c));

  }

}

---

I understand the part about it having to be my account, and it starting with /skin and then the color, but I don't understand how the

NPC Code:

---

setcharprop #C0,#T(#e(6,-1,#c));

---

makes it all work. Thank you for your help.
