One needs more translucent and the other more pearl.
The one color (Dead On Orange) is opaque enough although I could probably add a drop or two of red to it to make it stand out better.
The Fire Tiger isn't really neon enough to be a real fire tiger orange and I experienced a bit of buyers remorse on that one. I was hesitant to add even more white pearl powder to it. 1/4 tsp is normal for a cup of plastisol if that is the primary method of adding color. I added about 1/8 tsp total during the video and I think if I add a full 1/4 tsp it just might come out looking like an orange creme.
I could've checked my color wheels ahead of time, but where is the fun in that?
