• Resource for testing foreground-background color contrast: https://contrast-finder.tanaguru.com/ also https://webaim.org/resources/contrastchecker/ and https://colorbrewer2.org/#type=sequential&scheme=BuGn&n=3 (last one I just learned about). There's also a Chrome WAVE extension
  • Another one: https://coolors.co/contrast-checker/667faf-1f2129
