The systems and methods can determine a Daltonization value based on the color palette of a frame in the digital media and modify a local contrast parameter and a local brightness parameter of the frame by applying an enhanced Daltonization process to the frame. The enhanced Daltonization technique can create a color shift in the frame. In some embodiments, after the frame is optimally Daltonized, the local brightness and contrast parameters are rebalanced to shift colors back to light hues to compensate for the initial shift to darker colors. The systems and methods can return the optimized frame to a colorblind person for view. ## Claims ### Claim 1 A method for automated image processing to improve visibility of colors having similar luminosities in a digital media application, the method comprising: under control of a computing device comprising a hardware processor configured to execute software instructions: identifying an image frame of a virtual environment in a digital media application;
