I have a friend who has vision issues. He has been able to fix most things so he can see them, but there is one place he cannot see. This is the quest log. We are trying to figure out how to remove the parchment when you look at the quest log. Right now it looks like this:
Just trying to get the black background with white text. We know about immersion, and it works great when talking to the npc. It’s just when he looks at the quest in the quest log that the parchment remains. He just can’t read the text there.
I wish it did. His eyes cannot see text on light colors. This turns into a huge glowing box to him with blurry images blobs inside. Thus that makes it worse. He needs light text on a black background. We have tried every option in the settings of the game.
That sucks. You could check if there are any quest log addons which could make it readable for your friend.
From full UI reskins, I think for example ElvUI changes whole UI to dark background and light text but it might be too much, but maybe worth checking out. I haven’t personally used ElvUi so I can’t vouch if it can do this.
I also recommend to write to the Accessibility email here so that Blizzard may create additional options in the future, so everyone can play their games.
In the meantime you may have to rely on addons as Grelier posted.
