In all honesty, it would be an incredibly illogical and stupid decision to put a white logo there. Firstly, because the colors should be blue, red and yellow, obviously. And secondly, because this is not a matter of sticking to the original logo in terms of color, not even design. If their logo was white (which it is not) and they were really anal about keeping it white everywhere, then the away and 3rd kits would have a white logo, as well. Their logo is dark purple-ish and gray, and has other parts in it, so all of this obviously has nothing to do with the company trying to keep the logo authentic. There's literally not a single reason to make the logo white. But I wouldn't put it past the people in charge (whoever they are) to make a stupid decision.
