What does fresh blood in stool look like?

I know from the title this sounds like a silly question. But I have seen parts of my stool (solid stool, not diarhea) look red. Not the whole thing, not in one particular place, and I didn't see a pattern. The red portion wasn't any more liquid or solid than the rest of the stool. The water didn't change color to red. If I see jelly bean sized parts of my stool as pinkish/red should I assume that this is blood or food? I ate Sushi, a Spicy Italian sub at subway, an Apple, and a Fiber one bar today if that helps. Only drank water.
