Colorbox.io - version 1 is no longer available (heroku).

Algorithm for generating colors was open-sourced, but not the app itself.

I added 'denim' which does meet the 4.5 contrast ratio.

I moved the legacy blues into the 'safetyinsurance.com additional colors' section. The goal would be to retire these colors.

I checked out the app and came up with this page:
