Red means some RAM is failing! Plus I found one time on 2.8 Mac Pro with a Mini pot connection to a display. After a quick power outage it would't start all. I discovered if I unplugged the mini-display cord then it boot right up normally! Then after it started booting I plugged the cable back into my Mac Pro!
