Making LTSpice pretty

Color theme

You can change the default color palette of LTSpice. The default one is very depressing. I use a black and white theme with waveforms color scheme from MATLAB.

Colors can be changed using GUI or by modifying the values in the config file.

OS	path
macOS	~/Library/Preferences/LTC.LTspice.plist
Windows	%USERPROFILE%\AppData\Roaming\LTspiceXVII.ini
Linux	~/.wine/drive_c/users/$USER/Application\ Data/LTspiceXVII.ini

macOS caveats

Do not try to edit the macOS .plist file as it is just a pretty-printed version of a binary file. johan162 made a color theme manager script to simplify theme changes on macOS. The script comes with a few themes. You can add your own theme to the ~/.ltspice_themes/themes.ltt list and set that as default. This is what I use:
