Abstract: Composition having a blue color including a buffer, an anthocyanin, and a divalent ion source. The composition may comprise an anthocyanin and a divalent ion source, wherein the average variation of ΔE*ab of the composition is less than 30% of the average variation of ΔE*ab of a control composition after exposure of the composition and the control composition to a 400 to 765 W/m2 light source for a period of time. The composition may comprise an anthocyanin and a divalent ion source, wherein the composition exhibits a less than 20% change in the area beneath the reflectance colorimeter spectral curve of the composition from 430 nm to 530 nm measured over a period of time. In another aspect, a method of stabilizing a blue colorant is provided. The method may comprise combining a buffer, an anthocyanin, and a divalent ion source.
