I was curious as to what symbol could be made using the negative
spaces from the Autobot & Decepticon insignias. This turns out to be
the rough result. The colour of this insignia (I’m just gonna dub as
AuDe for tagging purposes) is the result of mixing the Autobot red +
Decepticon purple together, I have many results of such mixing hereand here and here .
And my insignia tag is here.
