<br>
I have kind of "silly" questions about the variable "colors" in the<br>
script polyg_8.ncl.<br>
colors = (/10,30,38,48,56,66,74,94/)<br>
<br>
Where do I find which color corresponds to each number. I looked at<br>
the web page on color tables but did not find it.<br>
<br>
Many thanks,<br>
Laura<br>
