DaltonLens

DaltonLens is a utility to assist colorblind people by providing color filters and highlighting tools. It is especially useful to read color-coded charts and plots. Here are the main features:

• Show a pointer over your screen to get information about the color under the mouse pointer, including its name.

• Grab a screen region and apply color filters on top of it. They include the daltonize algorithm to transfer the color differences into channels that are easier to distinguish.

• Highlight similar colors in the region. This is especially useful for charts and plots, and it uses adaptive filters to better handle anti-aliased line plots.
