[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%)'
