Hi Ken, they are more red in color, especially when itchy. I haven't noticed any obvious blood in my stool, the odd time I would notice a little bright red blood on tissue paper but I put that down to a tear. I haven't noticed them getting bigger after a bowel movement, but they do get bigger when they are itchy and if I can fight the urge to rub them, I have used aloe vera to sooth the itchy which helps. I don't think I have been constipated to point where I would say to myself " I am constipated" I have attached a photo if that is ok, and if it is of any help to you. Thanks.
