Purple screen tools are digital or software utilities used primarily in media production, design, or troubleshooting environments where purple screens indicate specific functions or errors. In video editing or live streaming, a purple screen can act similarly to a green or blue screen, allowing editors to key out and replace the background. In tech diagnostics, however, a purple screen may signal a system crash or software bug—especially in systems like VMware, where a Purple Screen of Death (PSOD) reveals critical system faults.
