Colorful Tooltips is a 1.12.2 mod that allows you to add an infinite number of tooltip color conditions via mod compatibility, GroovyScript, or even Crafttweaker.
In Colorful Tooltips, unique tooltip colors only activate when a specified condition is met, such as an item being in the oreIron ore dictionary, or having the Uncommon rarity.
By default, all item rarities (including Botania's Relic rarity) are given tooltip colors that match their text. (this can be disabled in the config)
In Crafttweaker, tooltip configuration is limited to only ingredients, so you can only use mods.ColorfulTooltips.add(0xFF0000, <ore:ingotCopper>) or mods.ColorfulTooltips.add(0xFF0000, <minecraft:apple>)
Eventually™ I'll add information for mod compat and GroovyScript.
