Better Rainbow Outlines Resource Pack (26.1.2, 1.20.1)

Better Rainbow Outlines Resource Pack replaces the standard block selection line with a bright, shifting rainbow border. It gives any targeted block a clean color cycle that stands out against both dark caves and bright skies. The pack also updates debug hitboxes with the same multi-color style when turned on during play. It leaves vanilla block textures untouched while making it simple to track where your crosshair points.

• Functions on all standard blocks as well as modded blocks.
• Maintains quick performance through a lightweight setup.
