The top answer makes a substantial omission. Red-green color vision deficiency is not even considered (the most common one).
In this case blue and green are excellently distinguishable, but red and green not in every case. The color chart is not really easy to distinguish at all.
Also if common, color blind is a misnomer, because usually people see those colors, just that certain shades have a higher contrast than others. And colors that are clearly distinct for "normal" vision, can be clearly distinguishable for people with so called color vision deficiency (such as more shades of yellow).
