Choosing a Theme
You can set a theme for Harlequin, passing the name of any Pygments style to the --theme or -t option.
Depending on the number of colors supported by your terminal and shell, some themes may not look great. For any terminal, we can recommend monokai (the default), zenburn, github-dark, fruity, native and one-dark.
$ harlequin --theme one-dark For a gallery of many of the better-looking themes, see the homepage.
