That would be awesome
I'm not sure if they do it.
On some flips I see: 1910 E98 Set of 30
On others: 1910 E98 - Color
I'm also waiting for PSA to start differing with E92 Crofts Candy colors too.

Edit: I'm not sure about the color difficulty on E98's, but if I had to, I would say from easiest to rarest:
Red
Green
Orange
Blue
