Classic candies you know and love, like Skittles and Sour Patch Kids, apparently contain unsafe amounts of titanium dioxide, which provides brightness in color to the product but is potentially harmful to the human body.

A proposed bill — Bill AB418 — is making its way through California legislation that would prohibit the sale, manufacture, and distribution of food containing titanium dioxide, red dye 3, potassium bromate, propylparaben, and brominated vegetable oil. Of those food additives, brominated vegetable oil, potassium bromate and titanium dioxide are already banned in Europe.

The bill was first introduced in February by Assemblyman Jesse Gabriel. If it goes into effect, many companies will need to change their ingredients containing titanium dioxide or the products won't be permitted to sell in the state.

Substances like titanium dioxide are linked to cancer and organ damage and can be harmful to DNA, according to the Daily Mail.

California, your chance to "taste the rainbow," may be coming to a close sooner rather than later.
