This pack adds 9 new colored TNT texture on top of the original one! The textures are based on the Official New Default Pack V2
To use the pack, make sure you have Optifine installed, turn Alternate Textures ON (You can find the Alternate Textures setting by opening Options>Video Settings and by looking in the right column, just under "Use VBOs") and put it on top of your other packs in the Resource Pack menu.

Not only does it serve an aesthetic purpose, it also helps you aim
better in Bow Spleef because you can clearly distinguish one block from another and
you can easily tell where's the intersection of blocks which is
important if you want to do 2x2 holes in one shot.

It is even more important when fighting in long-range archery battles
because a regular TNT texture would blend in with others and you'll have
a hard time seeing exactly the block on which your opponent is standing
on. With colored TNTs, you know where to aim to trigger a chain
reaction that will ignite the TNT your opponent is standing on.

NOTE: Despite what it says, this add-on pack also works for 1.8.9!
