According to FDA labeling regulations, any color that is being added to a food would not be considered a "natural color". This is irrespective of whether or not a color is derived from natural sources, such as plants, or as in this case, insects. Colors may be labeled by their common names, such as annatto color or beet powder. Alternatively, they may be labeled as artificial color or color added. This applies to many colors of natural derivation. For colors that are synthetic dyes, there is a process of registration by those manufacturers that certify the colors. All certified colors, such as water soluble Yellow 5, Yellow 6, Blue 1, and the corresponding oil soluble lakes, must be labeled by their names. Some of these substances have also had reports of health concerns, and are not allowed in some countries. The emerging response to this has been the availability of colors from natural sources that were not used before, such as purple carrot powder, grape extracts, radish extracts, and other things that might give people more peace of mind in their consumption.
