Will stool will be in different consistancy and color every day?

Yes...: Depends on the type of food, hydration, timing and underlying digestive or assimilation problem

Should be ~same.: You stool should be predictable in consistency, color and schedule, assuming there are not daily and drastic modifications of your diet, and assuming there's not a medical condition that it making your stool change out of your direct control. Daily alterations in the color and consistency of your stool would not be considered normal.
