Having said before about rumor that Yamaha Fiat had plan to running more than a color scheme this season, not sure changes like what the vary livery they are talking about. This is now the talk re-surfaces.

If that is only like years before to use two traditional colors of Yamaha, i.e yellow and white, i don't think it can be concerned as vary livery, but rather to follow the old tradition to appear different on some circumstances.

Actually, now I believe that the blue-white Yamaha Fiat looks gorgeous amongst of theirs, although I have to say that color scheme being used by them on the paddock looks better than what's painted on bike.

I wouldn't mind if the new color is only playing about combination of the two blue and white, but if it appears in the middle of season totally different with it like red, black etc, it would be more seen as inconsistency.
