go-rainbow 
Extremely inspired by chalk.js
go-rainbow allows you to:
- Iterate modifiers and colors on a String.
- Use HEX as you wish.
- Use from Int as you wish.
- Use RGB as you wish (work in progress).
- Bring magical Rainbow on a String (work in progress).
Available animations, Name, Preview, :---------:, :------------------------------------------:, rainbow, on going..., pulse, on going..., glitch, on going..., radar, on going..., neon,
