My colon feels sore and is painful when I have a bowel movement but my stool has no blood and mostly good color. I do get constipated.

See a GI doctor. An individual over 40 years old with altered bowel pattern (constipation mentioned) and abdominal discomfort should see a health care professional for a detailed history and physical exam including a rectal exam and stool test for blood. A gastroenterologist consultation probably indicated as well as a colonoscopy.
Could be mild IBS. Drink enough water (8 8oz glasses) and consider an evaluation by your doctor. Mild ibs is possible ; often is treated w/out drugs - just lifestyle or diet changes. Best!
