This is a very handy solution, and it helped me better understand how to manipulate the colors in a bar chart. I would like to mention a minor point for those who want to implement this solution, which is that "cd" is a poor choice for a variable name, because it conflicts with a command keyword.

@us
I wonder why you always enclose between brackets the exclamation point (?!).
I somehow 'perceive' in a different way the written sentence...Just thoughts anyway.

i'm sorry!
i'm sorry(!)
