Is there a way to apply a color to the text in the report footer in company setup?

For example, we have a telephone number below and we would like the t: to be in red and the number in black.

t: +44 (0) 123 456 7890

Have tried various RML combinations such as &lt;fill color="red"/&gt; t: and also experimented in the RML Header section in the Header/Footer section with <fill color="red"/> inside the <para style="main_footer"> section but still not found an answer.

Thanks for any advice.
