Ever feel that enchanted items are boring, just being purple? And that it's weird that the XP bar is green, compared to the purple? Well, here's your pack!
This texture pack makes the glint on enchanted items scroll through various colors, sort of like colored stripes, in a rainbow pattern (look at the project icon to see it). And it also turns the XP bar into a rainbow gradient, versus a flat green. To get an example of what I mean, look at the images (no GIFs, sorry, I'm bad a recording).
No OptiFine needed, and should work for almost all versions of Minecraft (just like most other packs). However, the rainbow enchantment glint colors don't work in 1.12 and below (the XP bar still does, though).
A very little pack, but I hope you like it!
