Summary description: Simulation of color vision deficiency, using LuaLaTeX
Announcement text:
This is the first release of dichromacy on CTAN. It is a package for simulating color vision deficiency (CVD) in LaTeX documents. It is currently limited to LuaTeX. Except for loading the package, all the user has to do is to set the type of CVD via `\cvdtype{}` and the severity with `\cvdseverity{}`, for instance: \usepackage{dichromacy} \cvdtype{deuteranopia} \cvdseverity{0.5} The package will then automatically adjust the colors in the document to simulate the specified type and severity of CVD. This can be useful for testing the accessibility of documents for individuals with color vision deficiencies. Currently the package supports colors defined via the standard LaTeX color commands (e.g., `\color{red}`) as well as PDF images included via `\includegraphics`.
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/dichromacy The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/luatex/latex/dichromacy/
Thanks for the upload. For the CTAN Team Petra Rübe-Pugliese
CTAN is run entirely by volunteers and supported by TeX user groups. Please join a user group or donate to one, see https://ctan.org/lugs

dichromacy – Simulation of color vision deficiency, using LuaLaTeX
Simulate color vision deficiencies, including protanopia, deuteranopia, and tritanopia, in LuaLaTeX documents. This package provides a few simple commands that allow you to control both the type of color deficiency, and the severity of the simulation.
