Not all Decepticons have red optics. For example: Tfp! Breakdown has yellow optics and Tfp! Airachnid has purple optics, plus Skyfire has blue optics even though he was a Depection before he became an Autobot, some Autobots have red optics, like for another example: Grimelock has red optics in the G1 comics while in RID episodes he has blue optics just like Skyfire. See? Not every single Autobot or Depection has to have red or blue optics only.
