News:
I have made a new design for the palette, now it has all the new 1.6 blocks in it too.
Schematics can not store entities, so all the sign title dissapears, therefore the palette is now available in world files.

------------------------------------------------------------

Old:

This is a block palette containing every block with ID numbers that can be found in Minecraft. I found it very useful during building and selecting blocks for a build. Also it provides a very quick insight for a texture pack.

The left side of the palette cointains every vanilla block, and also some CTM (Connected Textures Mod) blocks, but most of the blocks are accessable with the middle click of the mouse.

The right side of the palette is higly CTM-dependent, and most of the blocks are only accessable with WorldEdit and VoxelSniper, and just a few texture packs use these blocks (for example Westeroscraft, Dokuecraft Creative Pack, Creative Node pack, Voxelbox Palceon pack), but it provides a very wide range of blocks. Most of the blocks in most of the texture packs will looks the same here, but each block has different metadata.

For viewing correctly the CTM blocks, you will need Optifine OR McPatcher, however a few (just a very few) ctm options are not available with Optifine, but I prefer using it because it accelarates the game a lot.

This palette is not perfect, it may has some error but i will fix those failures in time. Any suggestion and ideas is welcomed!
If you find useful the palette, please support me with a diamond!

A big thanks for the people who helped making the palette: spherefs, wanderwaffle, Shiggy, SebTsch, K1ll1er!
