Sim Daltonism is a color-blindness simulator for OS X. It filters in real-time the area around the mouse pointer and displays the result - as seen by a color blind person - in a floating palette.
- Very significant performance improvement: now using a filter based on OpenGL. You can watch a video in real time with more than adequate performance.
- "Transparent" window: the image you see is the filtered image of what is under the filter window. Click through the window to affect what's under it. (The follow-the-mouse mode from version 1 remains available too.) more...
- OS X 10.10 or later
