With the idea in mind of removing the harsh transition between light and dark themes, I decided to try generating the checkmark color based on whatever grayscale color has exactly the desired contrast ratio, and I ended up with these. This is not the current behavior in chromium like my last comment, this was just an experiment. I feel like they simply suggest that we should be using a black checkmark in most cases though...
