MATLAB Schemer is a utility that makes it simple to import, apply, and export color scheme themes for MATLAB’s user interface and editor. It enables transferring customized themes between MATLAB installations or sharing color schemes among users. This MATLAB package makes it easy to change the color scheme (a.k.a. theme) of the MATLAB display and GUI. Color schemes can be easily imported by running schemer_import at the MATLAB command prompt, without needing any inputs.
