The Jam Pack offers a fresh new look to Minecraft. But don't be fooled by the 'simple' part, this is no mere paintbucket-pack. Instead it brings a number of motifs, or common patterns to the table and uses them to give a unique look not found in anything you've seen before.
Some textures deviate from Minecraft's colour scheme and default textures more than others, like the Blue Netherrack and End Stone, whereas some textures fit naturally with your old projects and make them look even better than before.
If you don't like the hyper simplified items in this pack, then there is a version with no item textures you can download, so you can use the vanilla textures.
As always, feedback is welcome!
