THE GREY TOWER

On a related note, and as a point of interest, here is what RJ himself had to say about the "appearance" and sensations of channeling (taken from the question of the week section on Tor's website):

A channeler sees the flows as colored very faintly, according to which of the Five Powers is involved (red = Fire, Blue = Water, green = Earth, yellow = Air, white = Spirit), although the "feel" of the flows are also different to a channeler, so that a channeler can tell one from another without actually seeing them. (That is how someone can tell that somebody else has channeled, say, Fire and Earth, in their vicinity without seeing the flows.) It isn't a physical feel; you might almost as well say that they have different flavors. They appear to be smooth and nearly transparent, tinged with color.
