+### Tmux Color
+
+`tmux-color` returns a color for the current Pomodoro status.
+
+```
+# Active Pomodoro
+$ pomodoro tmux-color
+colour2 # Green
+
+# Finished Pomodoro
+$ pomodoro tmux-color
+colour1 # Red
+```
+
+Nothing is output if no Pomodoro is active.
+
+You can also define custom colors:
+
+```
+# Active Pomodoro
+$ pomodoro tmux-color --active colour166 --done colour165
+colour166 # Orange
+
+# Finished Pomodoro
+$ pomodoro tmux-color --active colour166 --done colour165
+colour165 # Purple
+```
+
 ## Status Format
 
 All commands which display the status of a single Pomodoro can take an additional `--format` / `-f` argument.
