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?
You could look at how Tecosaur does their splash screen, which uses SVGs and adjusts them based on the theme.
