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. This will open a GUI to select the file to import the color scheme from. If you are using a personalised color scheme in MATLAB, you may wish to save it for yourself so you can re-implement it easily if you reintall MATLAB. Or you may wish to transfer your personalised color scheme from one machine to another. This section describes the steps relevant in either scenario.
