Hi Thierry and Hadley,

Thanks for your help! I got it working almost 100% to what I want. My last
questions are simple I think ;)
1) How can I pass a label to colour and assign the color at the same time?
The auto-selection of colors is awesome for learning, but makes it harder to
see some patterns.
2) in regards to 1), where can I find a list of the possible values that can
be passed to colour=""?  I've seen in some examples "gray50" but when I try
it, it doesn't come out gray50, it just prints that as the label.  For
example, in my case, I could have 4 colors with 4 different shades of each.
Or maybe I can use word length and gray scale, and make longer words darker,
etc...

many thanks for your time helping me sort through this!
