Spectrum
|
||||
========
|
||||
|
||||
Provides for easier use of 256 colors and effects.
|
||||
|
||||
To learn more about text formatting, read [A Guide to 256 Color Codes][1].
|
||||
|
||||
Variables
|
||||
---------
|
||||
|
||||
- `BG` provides background colors.
|
||||
- `FG` provides foreground colors.
|
||||
- `FX` provides effects.
|
||||
|
||||
### Background and Foreground
|
||||
|
||||
Terminals support 8, 16, 88, and 256 colors. Check if a terminal supports 256
|
||||
colors with `tput colors` before use.
|
||||
|
||||
The following colors are supported.
|
||||
|
||||
- 0 to 255
|
||||
- black
|
||||
- red
|
||||
- green
|
||||
- yellow
|
||||
- blue
|
||||
- magenta
|
||||
- cyan
|
||||
- white
|
||||
|
||||
### Effects
|
||||
|
||||
Though there are many effects, most terminals support at least bold formatting.
|
||||
|
||||
**Not all effects work on all terminals; use them sparingly.**
