This pack outlines ores even though there are many other but this is my spin on it.
It also has an option to turn on outline of diffrent stones to tell them better apart like gravel and andesite. (this was in a pack that ive made but made them now seprate)
Select version for changelog:
Changelog

(1.17 tag isnt here on the site yet while am submitted this you cant use this version on 1.16)
But thanks for the suggestion
