Individuals with which deficiency would likely confuse reds and greens?

Individuals with protanopia and deuteranopia have specific deficiencies in their color vision that affect their ability to distinguish between reds and greens. Both conditions are classified as types of red-green color blindness, which is a common form of color vision deficiency.

Protanopia occurs due to the absence of the long-wavelength (L) cones responsible for detecting red light. This absence affects the perception of red hues and subsequently impacts the ability to differentiate between red and green colors. As a result, individuals with protanopia may confuse these colors, often perceiving reds as darker or similar to greens.

Deuteranopia, on the other hand, involves the absence of the medium-wavelength (M) cones that are sensitive to green light. This deficiency also leads to difficulties in distinguishing between reds and greens, as the green hues may not be perceived correctly against the backdrop of other colors.

In contrast, tritanopia is a less common color vision deficiency caused by problems with the short-wavelength (S) cones, which primarily affect the perception of blue and yellow, not red and green. Therefore, examining the conditions, both protanopia and deuteranopia directly lead to confusion between reds and greens, making the combination of both deficiencies the correct
