Have seen this called both Blue and White Snowball. The color is from the RGB, so IMHO it is blue. O-III was used for L. The drizzled version (here) was much better than the un-drizzled version.

It is very small: 1.1 Arc' in diameter on the long axis.

This nebula exhibits some evidence of an interaction with the interstellar medium, along with a characteristic central torus and outer halo. It may be similar to NGC 2371, but older and with a less constrained wind.
