Maybe Thanatos is correct. Annoyance can lead to them going back together. From what I have read this does not seem likely. I believe that the reason for the colours are 'static' from the pattern. In book 4, all of the T'V had to force themselves away from each other. They might have stretched the pattern and this could be static or feedback from the pattern.

I find it significant that Moiraine always dwelled upon the fact that the Pattern would force the T'V into their path. With the stretching of the pattern when they forced themselves away, they might have slipped out of thier destinies, or rather, the most likely path for them to follow.

Think of the T'V as magnets. The closer they get to one another the harder it is to pull away. Also, when the T'Vs are closer the combined pull of the Ta'verinness (can someone tell me the correct word?) increases almost expedentially. They have a strong pull on a larger number of people. When they are apart the combined pull is less, so they have a weaker pull on a smaller number of people. Because of the lesser effect, the pattern might be trying to pull them into a place where it can affect the right people to forward the 'plot'.

The idea of balance is good. If the T'Vs are out of balance, albeit in a good way, the colours could counter that, and try to annoy them into going where they want. Although the colours do not push, have you ever had an itch that annoyed you so much that you want to scratch it? The itch 'makes' you scratch it by being annoying. It doesn't cause pain, it... itches. The T'V might 'scratch' the colours by going together.

If the colours are interference then it could be caused by the T'V going into Finnland, which warped the pattern further (like reading a strategy guide, only both the strategy guide and the game are omnipotent and try to fool the reader) and caused this interferance.

Any comments?
