Naming a certified color

The naming requirement
A color additive or the lake of a color additive subject to certification shall be declared by the name of the color additive listed in the applicable regulation in part 74 or part 82. That is the rule for certified colors and it is not optional.
Two concessions in the same sentence
It is not necessary to include the "FD&C" prefix or the term "No." in the declaration. So "Blue 1" rather than "FD&C Blue No. 1" is sufficient, which saves useful space on a small jar.
But "Lake" is required
The term Lake shall be included in the declaration of the lake of a certified color additive, and the rule gives "Blue 1 Lake" as its own example. A lake and a dye are different additives and the label has to say which.
And an alternative name may be added
Manufacturers may parenthetically declare an appropriate alternative name of the certified color following its common or usual name. That is a permission to add, not a license to substitute.
The shorthand, and its exact scope
Color additives not subject to certification, and not otherwise required by part 73 to be declared by their common or usual names, may be declared as "Artificial Color", "Artificial Color Added" or "Color Added", or by an equally informative term.
Or named voluntarily
Alternatively such colors may be declared as "Colored with ____" or "____ color", filling the blank with the name listed in part 73. For a product where the color is a selling point, naming it is often the better choice anyway.
Butter, cheese and ice cream are carved out
Coloring added to those need not be declared in the ingredient list unless a part 73 or 74 regulation requires it for safe conditions of use, though voluntary declaration is recommended. Nothing in this group is one of those three.
