Icons, text labels, and border colours all reinforce the status — readable by everyone.
Colour blindness affects around 8% of men and 0.5% of women. Red-green confusion is the most common form. Any interface that relies solely on colour to communicate status, errors, or categories will fail these users. Always use icons, text labels, and patterns alongside colour.
