I use the attached patch for some "interactive slides" with babel.

(require 'color)
(set-face-attribute 'org-block nil :inherit 'fixed-pitch
                    :background (color-darken-name
                                 (face-attribute 'default :background) 3))

You might also set :inherit of org-block-{begin,end}-line.
