Bangkok Black

Hello all, I would like to get a pink ID card and a yellow book. What do I need to do and what do I need to get in advance? I have looked on Google and YouTube but it seems confusing and each report seems to just add to my confusion. Each video on YouTube gives a different way that the person got said items. Does the process differ depending on where you are in Thailand? is there meant to be a process that every office should follow? I could do this in Bangkok or Prachin Buri.
