I’ve fooled with this darn program more than I should have. Having said that I tried googling again today. In many other google searches it talked about this (seen below) config file. I would make entries and it was obvious it wasn’t reading it.
~/.config/redshift/redshift.conf
Today a search said it should be here (in the root of .config)…
~/.config/redshift.conf
And I’ll be darn that’s where redshift expects in on Mint.
