Not so simple unfortunately

sketch this out on a sheet of paper.

The blue ones must be smaller than the red ones if they are also square and 12 are to surround a red. You end up with 4 on each side of the red. Each blue side is half a red side.

HOWEVER!

Adjacent patterns share blue tiles so if it went on forever in both directions you would really only need half as many or 6 blues for each red. However watch out for the edges of the pattern.
