Hi Emma,
You can surely change the text color for the hyperlink within the text box. All you need to do is select the required text (hyperlink part only) in the text box > Click on the Text Color icon and select the desired color for the hyperlink. Further to change the underline color of the hyperlinked text, use the underline feature to match the hyperlink color.
Hope this resolves your concern.
