Blue and Red for each set of nails.
Both sets of nails have similar patterns but with different base colours.
The choice of colours really depend on the significance or preference of individual.
Colours can speak loudly than words when colours in different cultures represent different meanings.
For Chinese, red is supposed to bring good luck during Chinese New Year so many Chinese would wear red clothes and put up red decorations.
Does red and blue have any meaning for your culture?
