Traveler's Dream resource pack is made for Open Terrain Generator presets called Traveler's Dream and Thaumic Traveler's Dream.
You can find all needed information on TD main page here:
You will need Optifine (MCPatcher may work,but I'm not sure about it, I prefer Optifine) for the resource pack to function.

Traveler's Dream resource pack changes:
v1.1
colors of sand and stone in some mountainous East biomes
v1.0
colors of sand and stone(vanilla ores too) in Cold Zone to resemble black volcanic stone and sands of Iceland;
color of sand in Jungle Zone, to make it reddish;
colors of sand and stone in Sunflower biome and it's hills-Yellow Rock, to make them look more like dark limestone;
colors of sand and stone in Barren Lands biome, to give them more "post-apocalyptic" look;
jungle leaves texture, to make it lighter and more convenient for bright coloring.
