When I change the colors using the Colorblind options in settings, it also changes your ally’s health bar to that color. It wasn’t like that on the last-last patch. It used to be white and I could easily tell when an ally is getting close to critical health. But now it just blends with the background, especially if I set it to green and then the lost HP is just a slightly more transparent green. It’s not really something I could easily see. The color change is good, it just affects my game sense a little bit as a healer main.
EDIT: The Ana ‘naded’ effect still is a little weird. Sometimes it wouldn’t show on my healing bar that someone is naded unless I look at the bar above my ally. It’s also hard to determine whether it’s my ally got a good nade or not because both healed and unhealable effects are both white in color.
