[Plugin: Tweet Blender] Change author font colour

Hi there,

I’ve worked out how to change the font colour of the tweets, but how do I change the font colour of the ‘author’? I tried adding font colour to this:
tb_author {
font-weight:normal;
but it didn’t work. I want the username colour to be different to the tweet colour.

Thanks
