[CONTENT] Link Colour CSS?

Hi There,

I'd like to know where I can override the [CONTENT] tag URL link colour for my email beautifier template please. I know I can add seperate CSS to the right side of the beautifier template but as it comes through in an email, as opposed to seeing the emails that beautifier attaches to in a web browser, I can't use Chrome Developer tools in the normal way, to find where the [CONTENT] tag URL link colour is coming from?

Thanks in advance.

Regards,
