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; identifying an initial value of a contrast and an initial value of a brightness of the image frame; determining a Daltonization strength, a local contrast parameter, and a local brightness parameter of the image frame; adjusting the contrast and the brightness of at least a portion of the image frame based on the local contrast parameter and the local brightness parameter; applying a modified Daltonization process using, at least, the Daltonization strength to modify color values of the image frame, wherein the Daltonization process creates a modified image frame; adjusting the contrast and the brightness of at least a portion of the modified image frame to create an enhanced image frame; and generating instructions for rendering the enhanced image frame in the digital media application.
