Is it normal to get blue fingernails when having a raynaud's attack?

Yes: The color changes in a raynaud's attack are "white" when the blood supply is decreased, then "blue" when the oxygen is mostly used up due to decreased blood flow being unable to bring in enough new oxygen, and finally "red" when the vessels relax and there is a reaction with an above-normal amount of blood flowing to the fingers.

fingernails only ?: Raynauds is due to the effect of temperature on the muscular lining of our extremities causing spasm. Fingernails are simply a protective covering of the finger end and so they will change color when the fingers do. It is highly unusual for the fingernails only to change in raynauds.
