[color]

Colors can be specified in many different formats, such as #RRGGBB, RRGGBB, #RGB, 'rgb(…, …, …)', 'hsl(…, …, …)', 'gray(…)' or simply by the name of the color. The identifier '-' can be used to read a single color from standard input. Also, the special identifier 'pick' can be used to run an external color picker to choose a color. If no color argument is specified, colors will be read from standard input. Examples (all of these specify the same color):
- lightslategray
- '#778899'
- 778899
- 789
- 'rgb(119, 136, 153)'
- '119,136,153'
- 'hsl(210, 14.3%, 53.3%)' Alpha transparency is also supported:
- '#77889980'
- 'rgba(119, 136, 153, 0.5)'
- 'hsla(210, 14.3%, 53.3%, 50%)'
