Hello.
I recently decided in my game to use a color-coding system for my Treasures. I did this because I had to have 3 chests with unique graphics to indicate, at a glance, how they are meant to be interacted with. I decided, "well, why not do this with all the chests? Maybe this will make getting to loot exciting?".
I really have no way of testing if this actually is exciting or not. I don't even have a way to know if this is an interesting concept beyond what I think of it (in other words, I like the idea, but I know I'm biased towards liking my own ideas). I'm not even sure if I've ever seen another RPG implement something like this.
I've currently got 4 Treasure Chests that show the kind of loot you'll be getting. Red Chests have Weapons in them. Blue Chests have Armor in them. Green Chests have Consumables in them. Yellow Chests have Currency in them (not just the standard currency, but also 3 other, more rare currencies).
So, what I'm asking is, does this seem at all interesting from a player perspective? Is it helpful in any way? Is it exciting to know that those three chests in the treasure vault have two weapons and a currency in them? Is it fun to see that Blue chest just out of reach up on a ledge? What do you think? Should Treasure Chests be color coded?
