Scholar Custom styling


I'm using the scholar theme, with custom styling. I'm using 4 main colours, two dark, two light. On the registration page, the questions regarding supporter, and setting up a blog are appearing with a dark font on the dark background, and you can't read them, I have changed all text in the custom styling page to black, and this hasn't changed the colour of these questions. Could you tell me what is the parameter to change this?

Also another issue I had was on the members directory, add friend is appearing twice.

Thanks for your help!
