Matteo's condition, where he can only see in black, white, or shades of gray, indicates a lack of color vision. This is typically due to an absence or malfunction of cone cells in the retina, which are responsible for color vision. Humans usually have three types of cones (red, green, and blue), and a deficiency in at least two types would result in an inability to perceive colors, leading to a condition known as achromatopsia or monochromacy. Rod cells, mentioned in options A and B, are responsible for vision in low light and do not contribute to color vision.
