Cool stuff. would be nice to have a color blind mode. I literally can't distinguish the red from green in this visualization.
Curious as someone that doesn't experience the issue but assumes that your system Accessibility settings, maybe high-contrast, would be useful instead of expecting individual sites to tailor their color palette... does that not work?
