DaltonLens can apply color filters such as the Daltonize algorithm on top of your screen. It is meant to help people with partial color blindness to see images differently and push the color information to the range of color that they can sense better.
It can apply the filters in real-time with little CPU usage, and is controlled by a menu in the system menu bar and global keyboard shortcuts.
Here are the current filters:
- Simulate the three common types of color blindness
- Focus the color information on the most informative color channels via the Daltonize algorithm
- Switch red/blue green/blue
- Invert colors
