I have heard 'burgundy' used strongly with a lot of WCs. I do not know if it's genetic, but yours looks similar.
I would say Het. Red.. but I don't see any alien head lines.
Your more experianced than me, so it's hard for me to say that it looks like a normal to me, if it may not to you. Either way, that blushing is awesome, and I love when they have thick blushed backs like that.
