It can be observed in the periphery, such as the fingers and toes, or centrally in the lips, tongue, and eyelids. Methylene blue is a medication used for certain medical conditions and is not related to skin discoloration. Raynaud's phenomenon is a condition where there is constriction of the blood vessels in the fingers and toes, causing pain and discoloration, but it is not necessarily bluish in color.
