The application applies a real-time color transform to the screen, in windowed or full-screen modes.
Simulations of the common forms of inherited red-green color-blindness (Deuteranomaly and Protanomaly) are available with severity ranging from the more common anomalous deficiencies to the dichromatic case.
For the color deficient viewer a number of color discrimination transforms are available: Daltonize; red-blue color swap; filters; inverse transform.
For more general use the application can provide the following color transforms: greyscale; brightness; contrast; saturation; color inversion; color swaps; color filters.
A circadian light block option is also available that prevents blue color output and reduces green.
As the color transform is applied in real time the application can be used with any media including video and games (if run in windowed mode).
