Colour Fill in Tables

Hi,

I'm designing an internal audit report template in Word 2000 and want
to have an 'assurance summary' table which will be a graphic way of
displaying our opinions as a bar chart. I'm doing this using a table
with the bars formed by table cells being filled in with a colour. The
problem is we have a corporate colour pallete that doesn't use the
standard colours in the pick list, and the process to pick the colour
isn't as straight-forward as it could be if you need to change it. (I
can hear people moaning about it already) .

Is there any way I can set the non-standard colour in the pick list or
as a customised button on the toolbar? I'd prefer not to use a macro
as our internal mail system won't allow us to attach any documents
with macros and this would make distribution for management responses
difficult.

Many thanks for any help you can provide.

David
