Rainbow XP Bar 1.16.3-1.15.2 is a small texture pack/mod created specifically to slightly change the experience indicator (XP HUD) to its rainbow counterpart. Additionally, this changes the color palette for the connection quality indicator (Ping)!
This is mainly done to diversify your game a little and make it more colorful. Something similar is used in the VanillaTweaks mod, but now you can use it as a resource pack or addon that does not require the installation of forge.
