colored bubbles could be messy

When we play with bubbles, it is just plain soapy water that just washed off and it leaves no stain. Now that Crayola came out with colored bubbles, it caught people's attention and leaves them bad taste - in this case bad stain. Parents complained about the stains after the colored bubbles burst.  Somehow there is a warning label but the words are too small to be noticed. I wouldn't read on something that is hard to get noticed. For the parents who have to clean up the mess, looks like they won't be using colored bubble anymore.
