Lightning/electric spark color

Do any of you know what colors to use to print a lightning bolt/electric spark color on black t-shirts?
The art is done in three colors and the center of the bolt is white and fades into a two blue shades.
Have you had success with this?
Fortunately I'm printing 100 cotton.
Thank you

For sparks or lightning you might find success printing 305 light blue and then a dark royal, maybe 300 or even a reflex blue. The 305 next to the white center of the spark is going to make the white glow more.
