Again, not sure why this works, but it does. You can spot this in action in a lot of MMOs where the text of the item is colored to denote its rarity. The player spots "purple text", immediately logs the information of it being purple, why, and what that means in context of the gameplay, and then can easily read the name or description or whatever follows without a jarring interruption.
Yea this specifically has been really reinforced in my brain.
World of Warcraft has conditioned me to equate color w/ certain rarity, even across other games:
Uncommon
Rare
Epic
Legendary
In fact, most games I see post-2004 that color their Item names seem to follow this tradition. It's almost become industry standard. I see several RM games use the same color scheme as well. Ofc, not every game follows this system, sometimes the colors are switched. However, whenever I come across a game like that, my brain gets super confused.
Using
@Sheklon's screenshots as an example:
Before I read the pic below this one, my brain had already assumed the
Splendid Flask to be
Rare,
Tsunami to be
Epic, and
Divine Clothes to be
Legendary. However, I was unsure about
Concentrated Perfume. My brain saw
Light Blue and thought...it's probably either a consumable, vendor trash, or something combat irrelevant, akin to a cosmetic item (since it's perfume, after all).

Then I clicked the spoiler and find out it means Uncommon Item lol...
Whenever colors are used for text, I always assume there's a system for what each color means. Otherwise, what's the point?
Edit: Btw, those 4 colors (
Uncommon, Rare, Epic, Legendary), unlike other colors, don't distract me in the least when read in text. This is simply due to over a decade of conditioning though. But I'm curious as to how prevalent this is.
However, in the case of your earlier post containing the green text...yes it was distracting since it wasn't in a place where I wouldn't expect to find Item Names. I'm starting to wonder if it's my being conditioned that I'm leaning towards wanting my numbers colored. Most game's color their numbers for pertinent info. Or maybe it's more correct to say that the numbers themselves often are pertinent info.
For instance, when I try the following w/ purely plain formatting all the way through...
Deals 9 - 11 Weapon damage with +50% Crit chance. In addition, reduces the target's DEF by 5 for 4 turns.
I find myself having to hover my eyes over the numbers for a split second longer to absorb the meaning of those values (well not really cuz I've already read that specific sentence many times, but you get my point). Like a part of my brain is screaming at me wondering: Why aren't those numbers emphasized?! I feel it's important to have a standardized color for the various numbers/values throughout skill descriptions. I created this thread in an attempt to find that color...whatever it may be.
