Tired of having only 3 fancy colors to choose? Want to make your materials glow like high-tiered items from popular servers? Just want to have some visual sense of progression?

ZSRarity adds an ability to select one of 16 default colors for your items as "rarity", which will make their names in GUI be colored!

To do that, write in your crafttweaker scripts:

<modid:name>.setRarity(colorName);
where colorName can be any of following (case doesn't matter):

red
blue
gold
dark_blue
dark_purple
purple
green
dark_green
dark_aqua
black
aqua
dark_red
light_purple
white
yellow
gray
dark_gray

But hey, Trashbox, I can just set color codes in language files. Why I should use this?

works in runtime: you can change rarity codes on fly to create complex effects
can be easily used in loops or other code
doesn't edit language files, which means than rarities from this mod work with every language without extra work
friendly color names will make easier to understand which color your item will take without looking at wiki

Limitations:

changing language will not translate ZSRarity-colored items to chosen language, you will need to restart the game

MaterialSystem support:

Due to how B.A.S.E./ContentTweaker handle creating material parts, the method this mod uses doesn't work.

To add rarity to those items, you need to use special class, named zsrarity.MaterialPartRarity.

This class only has one method: MaterialPartRarity.setRarity(MaterialPartDefinition part, string rarity), which will set the rarity to desired Material Part.

MaterialPartDefinition: just result of bracket handler <materialpart:material:part>.
