I'd like to be able to know how to change the theme's color. I mean, i don't really know much CSS, but I figure there might be a way to change the theme's coloring scheme.

I want to make my blog have a chocolate colored theme with the overall text a light brown color.

Here's my blog here.

any help would be much appreciated. :D

Go to Appearance/Atahualpa Theme Options/Overall Style and Config. There are many options there, including the background color, text colors, etc. You can do a Google search for information on CSS styles for fonts.
