The eyes are the same red as the wings... but they look darker since they're always in shadow because of his brow.
Spent a bit more time with it tonight and had my Starscream side by side to check the shoulder assembly as noted
here.
It's definitely misassembled:

Thankfully it doesn't prevent transformation, but it was the cause of my transformation issues - you'll have a little trouble squeezing his hands past his groin, and have to forcibly attach the wings to the arms unfortunately.
I actually took apart both toys at the torso, to see if there was any remould on the sliding track mechanism (now that it stays in place better in robot mode). I could only see a ~2mm difference in one spot... not big enough to clearly photo. It didn't even really look like enough to make a difference, but something in there does!
