A short explanation claiming that eye color (brown vs blue) can alter visual perception. It states blue eyes have less iris pigment, making them more light-sensitive and possibly perceiving some colors differently, especially in dim light; brown eyes purportedly let in more light and may perceive colors more vividly in bright lighting. The text connects pigment, wavelength/amount of light, and retinal cell registration as the mechanism.

Did you know that people with brown eyes versus blue eyes might actually perceive the world slightly differently? Brown eyes and blue eyes can both perceive many colors. Blue eyes are more sensitive to light than brown eyes because blue eyes have less pigment in the iris to absorb the light, and our perception of color is all dependent upon the wavelength and amount of light that is registered by the cells in our eyes. So blue eyes might perceive some colors slightly differently. Brown eyes let in more light than blue eyes, which might make it easier for people with brown eyes to perceive colors more vividly and deeply than those with blue eyes, especially in bright lighting. However, while people with blue eyes may be more sensitive to light, this might actually allow them to see better at night or whenever there's dim lighting.
