Blue Long Spark Material from Particle TrailRenderer Manual?

Does anyone know if the Blue Long Spark material shown in the Particle Trail Renderer manual page is available in an existing package or link somewhere?

I don't think there's anything special about it. Just use a particle texture and set colors to blue

2 years later and I am trying to get a nice trail renderer like that… Set it to blue and no dice. I used the Mobile Assets and found a Spark that I tried.
