[Harlowe 2.0] Can't change color scheme to the old one.

Hi. I'm new to twine.

Harlowe 2.0 use black-on-white color scheme, but i want to change it to the old color scheme (white bg and black text). I'd found this code in the manual:

(enchant: ?page, (text-colour: black) + (background: white))

, pasted in a header tagged passage, but styles for background and text colors from a <tw-enchantment> tag get overwritten in the <tw-passage> tag inside the <tw-enchantment>. Are there any suggestions?
