Blues dots are npcs who give you something or have special dialogue (they're like Easter eggs), while the green dots are quest related npcs. Regarding the dialogue options: the yellow lines proceed from the current menu, so always go to them after you've used the whites ones. Be advised that it's not necessary for you to use all the white lines, you should stick to the character you're playing regardless of the dialogue options offered. For example, my Geralt seldoms asks NPCs for information on political matters.
Thanks. I figured the green dots were quest-related, but sometimes I see them and the NPCs don't actually say or do anything.
As for the dialogue, what do you mean "proceed from the current menu"? Do you mean it opens up new dialogue options? I've seen that happen, but I didn't notice if it was the result of a yellow line.
I guess what confused me about the dialogue was a recent quest I just did. Speaking to the NPC, there was a yellow line and two white lines. The yellow one didn't really advance the quest as I thought it would (as some of them do), and the white ones actually DID advance the quest (in two very drastically different ways) and they were mutually exclusive.
I've gotten into the habit of choosing the dialogue options that fit with my character first (as you suggest), just in case I can't go back and choose the others. And yet, sometimes I CAN go back and choose everything. I guess there's no way to know when you can and can't do this, though, because the yellow/white colors don't seem to have anything to do with it.
