I probably won't. You can overwrite any color in scheme.less, though, if you download it and play around with it. You can also tweak things like the theme's contrast, and the breaks where it considers things "light" and "dark". My big wishlist item is a "Download current theme's CSS" but that's pretty tricky to do. If it had something like that, I'd consider making the preview tool more powerful.
