Safe to add food coloring to betta's water?

I am wondering if there is any risk to a betta fish at all of adding some food coloring to his water? We have been pulling minor pranks on a coworker and many on Fridays have revolved around a fish and I am thinking adding a couple of drops to make a light tinge to the water would be good if it posed no risk to the fish. Everything I've googled looks like it is fine, but really trying to cover my bases in advance.
