1. A system comprising:
a chassis;
a first optical filter and a second optical filter, wherein: (a) the first and second optical filters are both included within the chassis, (b) the first optical filter has a first color and the second optical filter has a second color, (c) the first color is defined by a first red, green blue (RGB) value that is based on a combination of a first red value, a first green value, and a first blue value, (d) the second color is defined by a second RGB value that is based on a combination of a second red value, a second green value, and a second blue value, and (e) the first RGB value is unequal to the second RGB value;
at least one non-transitory machine-readable medium having stored thereon data which, when used by at least one machine, causes the at least one machine to perform operations comprising:
storing the first RGB value in the at least one non-transitory machine-readable medium;
displaying an image on an electronic display while a line of sight between the electronic display and the second optical filter is obstructed;
changing a first display characteristic for the image based on the stored first RGB value, wherein the first display characteristic includes at least one of RGB value, transparency, contrast ratio, brightness, or combinations thereof;
receiving a communication corresponding to a user being unable to recognize the image based on the changed first display characteristic;
storing the changed first display characteristic in the at least one non-transitory machine-readable medium;
conducting optical training with the user based on the stored changed first display characteristic.
