Tritan color vision defect corresponds to which deficiency?

Explanation:
Tritan defects involve the short-wavelength (S) cones, so the deficiency is blue-yellow. Problems with S-cone function disrupt how blues and yellows (and some blues vs greens) are distinguished, making blue-yellow discrimination particularly impaired. By contrast, red-green deficiencies involve the L and M cones and are far more common, while a complete lack of color vision would be achromatopsia, not a selective blue-yellow issue.
