Well, I wasn't referring to just websites. Any software you make is probably going to have some kind of accessibility issues. For example, does your app have color cues for anything? Colorblind people may have an issue with that and so you need to take that into consideration and make the app colorblind friendly as well. It's virtually impossible de-conflicting all the types of colorblindness, so usually people just use icons to tag things instead of colors. This is even more important for things like games where colors indicate critical functions (hence why games sometimes have "colorblind mode")
