The Unity icon in activation windows does not follow our brand guidelines(see
“Inverse version of logo is white. This is suitable for dark and black bagrounds
http://unity3d.com/company/public-relations/brand).

It does not look nice and it does not support our brand identity, which we "pay" a lot of attention to else.

we should consider to change it since we are exposing it to every single user who install an activate our product.
