Description of problem:
Currently, the colour used by RHGB are hard coded into the binary. This is an
RFE for easy customisation of the colours, by using a simple configuration file
in /etc. This could also facilitate other customisation such as custom logos, etc. 

Version-Release number of selected component (if applicable):
ALL

How reproducible:
Always

Steps to Reproduce:
1. None. RFE only.
2.
3.
  
Actual results:
Hard coded colours.

Expected results:
Customisable colours.

Additional info:
Although this is relatively easy to customise and rebuild from source, its still
a minor annoyance. Please consider this RFE.
