The limitations of rendering technology should not be an argument against an encoding. We have characters that differ only in their properties, such as word-breaking and line-breaking. In this case, it may be argued that their colours apply only to their 'plain' colouring. Who determines what their colour should be in blue text? (Font technology seems to dictate that their colour is unaffected by the choice of foreground colour.) Richard.
