It really depends, there is certain foods and supplements that can change the colour of urine, I am unsure if this could be happening for you. But in general red pee could mean that there is blood in the urine which is not good.
I would recommend seeing a health care professional for a check up to see what is causing this. Usually they can do simple tests in the clinic to see if the redness is caused by blood.
