This is a PlaceholderAPI expansion that adds placeholders to it. The expansion has two placeholders (so far) to display the text with rainbow (or custom) colors.
Return the text you set instead of <Text> with the rainbow colors (Red, Gold, Yellow, Green, Blue, Dark Purple) for each character.
For example: %RainbowColor_This is how it will look like%
return the text you set instead of <Text> with the custom colors you set for each character.
For example: %RainbowColor_custom_a,f,e,b_This is how it will look like%
You can download this expansion automatically using PAPI download commands:
/papi ecloud download RainbowColor /papi reload
Or you can download it manaually from the eCloud and then put it in the expansions folder (Path: /plugins/PlaceholderAPI/expansions/)
