Hello!
Posting this after a brief discussion to see if it's possible.
Problem Statment
As a player, scrolling through multiple wands to find ones you can use is a bit frustrating, more so in the case of looking for wands that exist across both caster groups
Suggested Improvement
At creation of wands, read from caster the highest CL (Presumably what invokes the wand creation + restrictions), and apply wand colour 1 or wand colour 2 depending on the creators class(es).
Result
Wands created by Arcane classes look visually different to wands created by Divine classes, offering an at-a-glance feedback on if the shop contains useable wands for players based on their needs.
