noob pvp question

according to this page http://www.lineage2.com/Knowledge/cp.html a purple killing purple dont take karma.

But what if i hit a purple (sometimes automated player become purple) and while i hit it, it become white again (since automated player doesnt fight back) ? will i go red after killing it ?

Dont know if that make sense :p

Yes, you'll go red.

Thanks ;)

yea if it starts flashing its time to stop VERY soon or red you will be
