English:
When encountering the black logo, click the "light" button to switch to dark mode, and the black logo will be completely invisible (demo website https://img.run/ )。 It is suggested that the next version should be updated to add the option of setting logo in dark mode and white mode separately.
At this time I won't consider this a bug because it is just a caveat of the implementation. As the tone toggle is just a change in the class implemented by the html block, you can easily add your own CSS rules to alter the colors of the SVG logo.
