Error in one of the sentences

There is a sentence in Applied Accessibility: Avoid Colorblindness Issues by Using Sufficient Contrast that needs to be corrected. I was always taught in school and at work to always put the person before their disability, meaning “The person who is blind” vs. “The blind person.” It is just sounds less derogatory (not sure if this is the correct term to use) because they are still people and their disability shouldn’t be what describes them. I’m sorry, I don’t mean to be disrespectful at all.

First paragraph. Last sentence.

Second, foreground and background colors need sufficient contrast so colorblind users can distinguish them.
