Colours not right for fields and methods

Hi, using VS2003, R#259

Fields and Methods are only ever coloured with the 'field' and 'method' default
colours and never with the other sub-sets like 'implements' and 'overrides'
and 'hides' etc.
The icons on the left margin are shown indicating that R# knows that they
are - but the colour stays default!

Am I missing an option somewhere or is this a bug?
