Why is Exar Kun's Sith lightsaber blue?

For real, though. Exar probably did carry it over from the Jedi days. OK, think of it this way:

Have a lightsaber that you have used forever and ever and it has been so faithful to you.

or

Get some new lightsaber that you have never used before made by your underlings.

The color of a saber does not equate to one being a sith or jedi, it is preference. Why is it blue? maybe Kun liked the color blue.
