Gnuplot generates SVG images in Org Babel as shown below.
In the left solarized-dark theme, the SVG images exhibit a brown background that blends with the dark theme, resulting in very reduced visibility.
Conversely, in the right solarized-light theme, the SVG images display a pleasant light-blue background, offering excellent readability.
How can SVG images be displayed with a light-blue background in the dark theme, as it is in the light theme?
