[enhancement] Use different color for command usage examples within messages

#### Current Behaviour:
When a command is to be shown in a message as a usage example, the current way is to use backticks (`) to enclose it. This is hard to read as the rest of the message is of the same color.

#### Expected Behavior:
Use a different color for the commands and a different color for the rest of the message. This should be done by using a function to parse the string, fetch the substring within the backticks (`) and return a complete message as expected with the part in backticks being shown in a different color.
That is:

As red, yellow, white and green are used for other types by convention, I think cyan (as shown above) can be a good choice.
