Under Prismatic Wall, the first 3 layers all have a reflex for half save.
At 2nd level and higher, a rogue can avoid even magical and unusual attacks with great agility. If she makes a successful Reflex saving throw against an attack that normally deals half damage on a successful save, she instead takes no damage.
Evasion normally applies to anything with a Reflex save for half damage, so yes, it should work. Won't do you a lot of good, though, because the last layer is going to disintegrate you anyway.
