Based on the scenario, which type of photoreceptor cell is primarily responsible for the individual's successful performance in the first part of the experiment? Explain your reasoning by linking the cell's specific functions to the tasks described.

Cones are a type of light-detecting photoreceptor cell that functions optimally in bright light. They are crucial for perceiving color and are responsible for high-acuity vision, providing excellent spatial resolution and sensitivity to fine details.

Ganglion cells are neurons located in the retina that receive visual signals from photoreceptors, such as rods and cones, via interneurons. The axons of these cells then converge and exit the back of the eye to form the optic nerve.

The trichromatic theory of color vision proposes that color perception is mediated by three distinct types of cone cells in the retina. Each cone type is maximally sensitive to a different wavelength of light, corresponding to red, green, or blue. According to this theory, the full spectrum of colors we perceive is produced by the brain interpreting the combined signals from these three types of cones.

Based on the case study provided, identify the type of light-detecting cell that is most likely impaired and justify your answer by connecting the individual's specific visual difficulties to the primary functions of that cell type.
