These modes simulate the different types of color blindness.
This mode simulates red-deficient color blindness, where the L cones are absent, causing difficulty in distinguishing red from green.
This mode simulates green-deficient color blindness, where the M cones are absent, causing difficulty distinguishing green from red.
This mode simulates blue-deficient color blindness, where the S cones are absent, causing difficulty distinguishing blue from yellow.
These modes operate in split screen and full screen modes. The split screen version shows the unprocessed camera image on the left, and the simulated image on the right.
