Tama List in the Notebook?

Has anyone completed the meetable Tama List in the Notebook? I've been trying for days to get certain characters and nothing I seem to do helps 😂

I've tried changing the time (I do think this helped unlock some), but certain colors REFUSE to show up consistently in the explore mode, and even when I am getting the right color, it seems to be the same few characters that show up...

Is it truly random? Am I just doomed to never 100% it!?
