Graphicals in Management reporting

Summary

Client requires custom colours with rules attached to each entity for variance waterfalls

Content

My client has specific RGB Colour guidelines they need to follow for each Entity in their Group reports.

Every month they have a variance waterfall between Actual and Plan

As these variances change the colours in each change needs to change (the colour has to match the relevant Entity).

They currently do this manually in excel, is an Oracle EPM reporting tool capable of doing this (without going to excel)?

This is a top 10 ASX Australian company - and many others would have this requirement.
