Color blindness generally makes it difficult to distinguish certain colors.
Disease description:
Today, while traveling on a business trip with a colleague who was driving, I found out during our conversation that he is colorblind. I felt quite worried. Generally speaking, which colors are most commonly indistinguishable for people with color blindness?

Color blindness, a visual impairment, is commonly characterized by reduced or complete inability to distinguish certain colors. The most common type is red-green color blindness, in which individuals have difficulty differentiating between red and green, potentially leading to challenges in recognizing traffic signals or identifying color-coded objects. Besides red-green color blindness, other types include blue-yellow color blindness and total color blindness (monochromacy), with each type affecting color perception differently. Causes of color blindness vary and may include genetics, eye diseases, or injuries. Although there is no complete cure for color blindness, affected individuals can improve their color recognition to some extent through color-assistive tools, special corrective glasses, and training.
