I have looked everywhere and i can't find anywhere in option the setting to turn on the colorblind mode.
If you are colorblind its very hard sometimes to play. I myself most times guess the color on things.
After talking to support about it they respond with:
Hello,
We're sorry to hear your experience with the game since we still don't have an option for colorblind mode.
We'll forward this feedback to the proper department for further review. Also, we encourage you to post this on our official forums since the Game Developers are reading the forum thread frequently. https://forums.bladeandsoul.com/forum/421-general-discussion/
