updates color generation, tries fixing credentials bug

- credentials still lost the refresh token after a certain event
  - this was now fixed by completely removing any saves past the first one
  - https://trello.com/c/iORYLYHl/44-1-check-on-credentials

- Color Coding is now updated
  - fixed an incorrect color mapping in the colors.json
  - updates some calls to functions to correctly get the natural colors
  - the incorrect red -> yellow mapping might have to do with the previous credentials error
