Sidebars : Different colour of fonts

Hi,
First I would like to heartily thank you for the great theme. I don't even know the difference between css and html, but could do some good work. It is a religious blog, see it here: www.anandbava.com

Now for the question: I would like to have different colour of fonts in each of the 2 sidebars. eg. White for the left and black for the right one. The widgets option is common to both, so can't do that there. Tried different things like setting it in Body, Text & Links, Sidebars but the effect is far from desired esp. in the right sidebar.

So do guide me,
Thanks again
Tikdi
