It is also interesting to note that the sensation that you receive
upon seeing a color may not be the same as the sensation received by
others seeing the same color. People who are color blind find it
difficult,
or even impossible, to distinguish red and green or yellow and blue.
When a person is red/green color blind do they see only red? only green?,
or a shade of color between the two?
