All lobsters whether good or bad will turn red after you boil/steam them.
To know if your lobster is good or bad. The part where the tail meets the back you want to break and make a hole for your finger to fit. Your finger should be going into the tail not going into the back of the lobster. On the roof you should feel the shell and then under your finger there will be meat if the meat is squishy not firm, messy, and gooey. Then you have a bad lobster. If its firm and pink it is good.
