colored bars

Hi I am wondering if I can make the accordion buttons each a different color. I want to have them in a gradual gradation of the same color, a hex color but I'm not sure whether the pro version will do that. I can get the box to be a color using css, but I can't seem to get the accordion bar/heading to take a color.

Thanks!

Yes, I saw the styling doc but it doesn't tell me how to do what I want.

I want the whole bar to be a color and I want to use hex colors with a gradation.

See example here.

I don't see how to do this in the documentation.

I will buy the pro version if I can do this either through the program or with css.

Thanks,

Joanne
