Color can change based on diet, based on the accumulated "sludge" on the colon walls being flushed out (usually only happens with the right combination of soluble and insoluble fiber, which is tough to get in a regular diet, particularly in kids who are picky eaters), or something like a cold or respiratory issue which increases mucus secretions that to through the stomach and are eliminated through the poop.
I'm a nutritional consultant so if there are additional changes you want to discuss, get back to me.
