Anyone notice this? the blue tilt makes your poop blue

so one day i drank 2 of those blue tilts.....next morning i took a solid blue poop,which was a little scary,i never seen or heard of blue poop.so my brother decided to drink a blue tilt that day and next morning he said there was a blue streak in his poop,anyone else notice this? perhaps the other colors result in different colored poop,and rainbow poohs if you drink every color
