Color Blind
The top three are nearly indistinguishable to me. 4 and 5 look very similar but I can tell some differences in shade on either of the ends.Color blindness can vary in severity. For you, the top three spectrums below might resemble each other, but the ones in the middle (protanopia and deuteranopia) will look different. For someone with profound red-green color blindness, the top five spectrums should resemble each other.
