Block particles not working

[Xerus]

I have a block with a jsn file. The texture is working fine but the breaking particles are this purple-black stuff, s not working. This is my json file:

{
    "parent": "block/cube_all",
    "textures": {       
        "down": "simpleautomation:blocks/farmerflat",
        "up":   "simpleautomation:blocks/farmerflat",
        "north":"simpleautomation:blocks/farmer",
        "south":"simpleautomation:blocks/farmer",
        "west": "simpleautomation:blocks/farmer",
        "east": "simpleautomation:blocks/farmer"
    }
}

Set the particle tag in the texture tag.

You may also set "particle" in a defaults segment, and you may set it to one of your faces (e.g. "#up").
