did you go to netherite mining in the nether but it was hard to locate the ancient debris between all the netherrack, gold and quarts? did you place the tnt 4 blocks gap but it was hard to count this with the netherrack texture? this texture pack is for!
the changes that this texture pack do is:

-turning the netherrack into iron blocks so it will be brighter and you can easily place the tnt
-turning the nether gold ore to gold block
-turning the quarts ore to bone block
-turning the ancient debris to diamond blocks so you can locate them more easily
