Blood: Perhaps from a haemorrhoid although there may be other possibilities (fissure, diverticular disease etc). Could be food as some will discolour the stool but medically it is safer to assume it is blood until proven otherwise. Need to have an examination by a doctor licensed in your area to sort out whether you are bleeding and where from +/- may need tests to sort it out.

Probably sauce: Blood in the stool has a tendency to turn the toilet-bowl water red, because unclotted blood disperses evenly throughout the water. Food does not usually retain its color in stool, but sometimes it does if it is not fully digested. This history suggests some partially undigested food. If persistent for more than 24 hours, evaluation is warranted.

Without: Any symptoms change in color of stool are usually associated with diet and should be no cause for worry.
