PSP8 question

I am having trouble with a pretty simple thing in PSP8. How do you change the color of brushes? So say I took a black text brush and wanted to have it a cream colored text. How would I do that? I have asked this question before, and the answers I got were 'just choose it as the color of the brush'. What I want to know is how to do that. I am stumped.

Thank you!
