Wall Street Journal:

Kathryn Albany-Ward, founder and chief executive of British nonprofit Colour Blind Awareness CIC, said colorblind people struggle to discern basic color-coded information in many experiences with technology, from reading maps online to figuring out whether the LEDs on a Wi-Fi router are blinking green or red.

Ms. Albany-Ward said colorblind people have historically been hesitant to raise accessibility issues in the way other disability rights activists have.

Apple in 2019 introduced a “Differentiate Without Color” iOS setting, which replaces interfaces that rely solely on color with noncolor alternatives. The company said it has supported customers with colorblindness for more than a decade with tools such as the iOS Color Filters setting, which was rolled out in 2016.

As is often the case, accessibility features benefit all users, not just the users the feature is designed for.
