Today we had a new player join who has difficulty seeing red/green colors and the tutorial gave them difficulty because of this. I suggest revamping the Tutorial so that the text in there is in a color spectrum that all incoming players can read and understand.
There are color blindness issues in a very small portion of the population. While I understand the sentiment, red/green color-blindness is going to affect a lot more than floating text. Then you have the colorblind groups that aren't the majority and are sometimes the opposite. There are settings/resource packs available for their use, but we can't really build everything to work for everyone unfortunately, unless we made it black and white only. In the future, if you direct them to guide.emc.gs, they may find that easier as an alternative option with the same info.
