Thanks for your feedback Travis. I will definitely work on the slash a bit more perhaps thinner. Great eye on spotting the colors! 
I’ll post the slash and impact separately so you can see the colors better and give me better feedback.
Slash trail only (Orange “fire slash” fades out at end, fade in fade out hints of whites at the middle for “wind”, fade in fade out hint of black following the trail for “smoke” because firey orange, darkred/maroon for a “bleedy” slash effect, holy distortion shader for distorted “heatwave” effect.)
Impact only: ( purple signifying slash hit, red flash, blood red, orange sparks from impact, blood red sparks/drops flying away)
Cheers.
