A lot of bosses use a wealth of traps and I find the yellow text to be the cause of a large amount of screen clutter. It’d be nice if the traps were standardized across all bosses and the yellow text removed completely. So say all Reduced Attack traps give off a pinkish aura. Any time a trap pops up with that colour, I’ll know what kind of trap it is after my first encounter with it (this also encourages players to test traps the first time they encounter them).
Using auras/effects/visuals to distinguish traps which are the same for all mobs in the game goes a long way to reduce screen clutter and makes encounters more interesting for players, since you have to consider what type of traps are active rather than just reading the (very cluttered) screen.
Also if you go the route of using auras/effects/visuals to distinguish trap types (e.g a pinkish cloud), you can use any graphics you want for the actual traps. So maybe two different bosses both use Reduced Attack traps, but the trap/totem itself looks different for each, to fit their themes or types.
