Board Thread:Speculation House/@comment-1173941-20130216005034

Figured i'd start a forum discussion about this, because, you see, if I were to put it on the wiki article, someone will put their own speculation, possibly over-write mine, and eventually it wouldn't be there anymore. Wiki's aren't great for sharing your speculations. That's what forums are for! :D

Anyways, currently we know that her rapier has 6 colors. Red, Blue, Yellow, White, Violet, Light Blue. In thar order (Clock-wise or counter-clock-wise doesn't matter, seeing as it's different from top or bottom... Just know, that those colors are next to each other XD)

Anyways, lets get to the discussion..

Please keep in mind, these are all speculations i've come up with, based on what I believe to have observed through watching the "White" RWBY Trailer. Even I do not claim to know the truth. 
 * Red - The most common speculations regarding the Red color, are that it either some how increases Weiss' strength, exponentially, or that it generates a powerful force-field, capable of repelling an attacker several meters back.
 * Personally, I find the first idea lacking. When her sword turned red, her sword didn't even collide with the Armor's sword, and she didn't move very much at all, leading me to believe she didn't push back on him. The force-field idea makes much more sense, and is probably even it...
 * But I have an idea that I like. What if red, in actuality, is a Thermal-magic based color? What if that wasn't exactly a force-field we saw, but more like an explosion of heat, that she used to act as a shield, and at the same time blow her enemy away? The "force field" looked more like a sort of splash to me. Also, moments later, we see her freeze the ground. Of course, this means that Light Blue isn't ice, but i'll get to that in a moment...
 * Blue - This one seems a bit more obvious to me. And I think it's also pretty obvious to others. To me it seems to be some kind of binding magic. We see it used at the end, when she locks the Armor monster in place. That's about all we got from Blue.
 * Yellow - Yellow... The most popular theory about the Yellow power (which due to some rendering error looks green on some frames of the trailer) is that it increases her agility.
 * I'm sorry, but i'm going to have to completely disagree. She already seems to be quite fast and agile, even before she uses her magic. We only spot her use Yellow, when she is on the Armor golem's sword.
 * My idea regarding Yellow is Attraction/Repulsion magic! Why's this? Because Weiss was able to become latched to the sword instantly, despite it moving extremely fast, and not even having to hold onto it. Additionally, we see it used to repel the armor up into the air. But wait, wasn't that Blue? No, acctually, it looked more like Light Blue. Which i actually have two theories for at the moment. Again, get to that later, but I believe I saw for an instant, the seal beneath the golem change to yellow, before repelling him upward.
 * White - This one is a bit interesting. We see her using white crests to air-step, as it's called, quite a bit, even before we're aware that her sword may be behind it. And in the end we see her sword's mechanism rotate, before all the colors glow white, and runes are shown along her blade. She then pierces clean through the armor, and it seems to shatter into pieces.
 * My theory regarding this, is that white is likely an acceleration type of magic, seeing as it allows her to jump great distances, at great speeds. And even at the end, when she uses it, it's really only accelerating her at great speeds, clean through the armor.
 * Violet - I don't really even see violet be used....
 * Light Blue - Light Blue is assumed to be ice type abilities, seeing as she seems to use ice to freeze the floor. But if that were true, my theory would be wrong... We can't have that!
 * Like I mentioned, I have two theories. See, we see Light Blue TWICE... When she creates the ice, and when the Armor steps onto the crest, and is projected upward! See, I think that Light Blue is actually an enhancement ability! It enhances the last setting she was using. Think about it. She used thermal magic to explode the air in front of her, and then enhanced it to freeze the ground down a line towards the Armor! The second time it's used, we see her use Yellow to attach herself to the Armor Golem, and directly after, she switches to light-blue, and we see a light-blue crest underneath, before she moves, dodging the armor, which ends up where she was, and we see the light blue seal under him, repel him upward! I vaguely remember spotting a frame or two with the seal blinking Yellow before hand!
 * My second theory is that she didn't use it to freeze the ground, and i'm seeing things, and she didn't use it to enhance the yellow, and i was still seeing things, but rather, that the Light Blue itself is what repelled the armor. Yellow and Light-Blue are on opposite sides of the sword, so it makes sense they have opposing abilities. And to add, perhaps the ice on the ground, was spread, due to the use of light blue repelling is forward..
