Styling Module

Crossterm provides options for you to style your font and terminal. Take for example coloring output and applying attributes.

Color support Windows systems with versions less than 10 will only have support for 16 colors and don't have any support for attributes. Most UNIX-terminal is supporting lots of colors and attributes.


There are 16 base colors which available for almost all terminals even windows 7 and 8.

Light Variant Dark Variant
Grey Black
Red DarkRed
Green DarkGreen
Yellow DarkYellow
Blue DarkBlue
Magenta DarkMagenta
Cyan DarkCyan
White DarkWhite

In addition to 16 colors, most UNIX terminals and Windows 10 consoles are also supporting more colors. Those colors could be: True color (24-bit) coloring scheme, which allows you to use RGB, and 256 (Xterm, 8-bit) colors. Checkout the examples on how to use this feature.


Only UNIX and Windows 10 terminals are supporting attributes on top of the text. Crossterm allows you to add attributes to the text. Not all attributes are widely supported for all terminals, keep that in mind when working with this.

Crossterm implements almost all attributes shown in this Wikipedia-list.
