To some of us who have problems distinguishing from one color to the other, the color of the quest givers' name(Orange? Light brown?) appears very much like the hostile red and can be confusing for new players.
I would recommend changing it to a different color like Topaz(Dim yellow) instead.
Additionally, I would like to suggest that a different color will be given to merchants so we can distinguish those from the normal riffraff and avoid spamming all of the NPCs in the region. Anything other than the current blue.
