You can use htmlText to assign colors, either by mnemonic name or by
numeric values -- assuming your list is tab-delimited for display in the
columnar list you could do something like this (off the cuff, but should
on DisplayList pList
put empty into tHtmlText
set the itemdel to tab
repeat for each line tLine in pList
get item 3 of tLine
if it > 0 then put tLine&"<br>" after tHtmlText
put item 1 to 2 of tLine &tab& \
"<font color=""e&"red""e&">"& item 3 of tLine \
&"<br>" after tHtmlText
put tHtmlText into fld "Display"
