9005 conversion is adapting a 9005 high beam bulb to fit into the 9006 low beam housing. Basically you are allowing the plugs to fit the bulb. From what I hear this is not the best way to go.

As for the color like the S2K it is the reflective properties of the projector that give it the color. The Kelvin rating for the bulb I believe is 4300K. From UBL you would want their 5300K kit.
