Amanda is completely colorblind. She sees everything in different shades of black. However, due to the differentiating shades of black, she can call each shade of black by its actual color. For example, she can identify that the dark black is actually red and that the light grey is actually white.
One day, Amanda goes crazy and murders her husband. When Amanda is taken to court, she says that her colorblindness caused her to lose her mind. The judge decides that she should be kept in prison until her color vision comes back.
After 12 years, Amanda's color vision comes back.
How can she prove this to the judge if she already knows how to differentiate colors?
Amanda can prove her regained color vision to the judge by demonstrating her ability to accurately identify and differentiate colors. She can participate in various color vision tests commonly used by optometrists and ophthalmologists, such as the Ishihara color test or the Farnsworth-Munsell 100 hue test.
During these tests, Amanda would be presented with specific patterns or arrays of colored dots or hues, and she would have to identify the colors or arrange them in the correct order. With her restored color vision, Amanda should be able to accurately identify and arrange the colors as expected by someone with normal color vision. This would serve as tangible evidence that her color vision has indeed returned.
Additionally, Amanda can also provide anecdotal evidence by describing her experiences with colors after her vision has returned. She can explain how she now perceives and differentiates colors in everyday life, providing specific examples of objects, nature, or artwork. This would further support her claim that her color vision has been restored.
