So I am color blind and have been using this site for a while. I just learned today that there is a different color shown for active(green) and inactive(grey) users on the bubbles next to their names. I could not notice the difference for weeks. Could we use a different set of colors? Bluish-green for active, red or black for inactive seems intuitive. BTW making the green a blue tint makes it easier for us colorblind folk to see it better. TY
