Assuming that c is a DiaColor object, the following Python code should
give you a "hexadecimal color value".

 '#%02x%02x%02x' % (c.red*255, c.green*255, c.blue*255)

I don't think that this is too difficult. You can wrap that in a 
function that takes
a DiaColor object as the argument.
And Dia is open source, you can provide a patch that adds additional 
functionality.
