PAMTRE BERRIES YO!
Mix a Pecha berry :P
there isn't a white pokeblock
The point of a pokeblock is by mixing berries in berry blenders together after mixing the berries you give a taste if the pokeblock is the right flavor for your pokemon and also It helps in pokemon contest and battles by raising your pokemons contest skill And the recomended pokeblock that you will have to make is the red pokeblock
In Pokemon Ruby,Sapphire and Emerald after you make a pokeblock, you can check the pokeblock case and you give the desired Pokemon the pokeblock to help it do better in Pokemon contests. After you have received a pokeblock case and you made pokeblock at the berry blending machine go to your key items in your bag and scroll down to your pokeblock case then simply select the pokeblock you want to give your Pokemon.
Make sure you have a pokeblock case and go in any contest hall and look for the blenders. Press A and you can berry blend, it creates one pokeblock.
Check each berries tag in your bag and look for bitter circled if this is the case use this berry in the berry blender and when your finished you should receive a green pokeblock.

First you must bet the PokeCase that carries PokeBlocks from someone in one of the Talent Show buildings. After that talk to an old man in the Talent Show building and he will ask you if you want to make a PokeBlock. Keep in mind that you have to have a Berry to make a PokeBlock!
