I just had the fun experience of checking New Relic’s status page and thinking everything was fine, and then minutes later having a colleague check it and announce an issue.
I have a common form of colorblindness, but still depend on color in many situations.
For me, the “Operational” and “Partial Outage” colors look the same, so a quick glance at the status page, and noticing a single “checkmark”, my brain assumed everything else with the same color was also had a checkmark.
If the “Partial Outage” color was confused with the “Major Outage” color, I think that would be less of a big deal. In order to do this, one proposal would be for the “Partial Outage” color to be much darker, so that if all the colors were converted to black and white, the gray for “Operational” would be light and the grays for the outages would be dark.
Maybe consider this a feature request?
