brewscheme now includes new Mata classes/methods to simulate the color that would be perceived by individuals with varying types of color sightedness impairments. Additionally, similar to brewviewer there is also an analogous program available to show how the simulated color values would appear called brewcbsim. Future development will exapand the options of both brewcbview (e.g., to handle multiple color tuples and display them in a single graph), brewviewer (e.g., to show a preview of specific palette combinations under varying forms of color sightedness impairment), to add the simulated colors to lookup tables used by brewscheme and brewtheme, and to create a proofer for Stata graphs that would show how they would appear under different forms of color sight impairment.

As always, comments, requests, and collaborators are always welcome.
