I was just annoyed that the tools where so much darker than the diamonds, At the same time I noticed how the armours still had a really dark outline so I changed that to the outline of the diamond as well.
I made an edit to the existing textures so I uploaded two extra versions.
Vanilla:
Shiny Diamond tools:
Shiny Diamond Tools, Dark border:
All "extra" textures (Like vanilla diamond or vanilla armor) don't exist in the pack since they're already in-game.
