Check out my new fav Minecraft texture and why...
The "LB Photo Realism" has now been released in an amazing x256 version. Yes you will need a super PC to run the game - yet using it does re-new a faith in god ^^
What you see above is the original MC texture quickly replaced by the brilliant and popular "johnsmith 32x32", that texture offers a better color and texture range on all the blocks without going too far from the original -just better water, moss colored cobblestone instead of that terrible turquoise green. I rely recommend this one.
Finally and if your PC is up to it - the ultimate texture seen last, no more problems with moss green or water here, only to enjoy. A brilliant range of color throughout and great for a change.
