You are right, but you may be missing the context I am coming from.
For me, the image is generated from latex fragment \(x^2=3D2\) by (1)
generating dvi file with foreground and background taken from 'default
face; (2) converting the dvi file to svg.
The tex file roughly looks like
\begin{document}
\definecolor{fg}{rgb}{1,1,1}
\definecolor{bg}{rgb}{0,0,0}
\pagecolor{bg}
{\color{fg}
\(x^2=3D3\)
}
You see that we set foreground and background explicitly.
The .dvi file still keeps the background color setting
> ...background rgb 0 0 0=EF=BF=BDcolor push rgb 1 1 1
However, after passing through dvisvgm, we background color information
is lost because the background is simulated by placing black rectangle:
<?xml version=3D'1.0' encoding=3D'UTF-8'?>
<!-- This file was generated by dvisvgm 3.4 -->
<svg version=3D'1.1' xmlns=3D'http://www.w3.org/2000/svg' xmlns:xlink=3D'ht=

<g fill=3D'#fff'>
<use x=3D'-14.536172' y=3D'17.344276' xlink:href=3D'#g0-120'/>

<use x=3D'8.910542' y=3D'17.344276' xlink:href=3D'#g1-51'/>
</g>
</g>
</svg>
Note that setting fill property directly will yield normal result in the
resulting svg:
<svg version=3D'1.1' xmlns=3D'http://www.w3.org/2000/svg' xmlns:xlink=3D'ht=
tp://www.w3.org/1999/xlink' width=3D'32.302787pt' height=3D'9.867978pt' vie=
wBox=3D'-16.60823 10.605991 32.302787 9.867978' fill=3D'#000'>
However, dvisvgm does _not_ use this method simply because it is not
fully portable - some browsers and svg viewers ignore fill
attribute. So, drawing background rectangle is often recommended for
svg. It is also apparently a common practice.

I am not sure if Emacs should behave differently in this scenario or
not. It may be a judgment call and may also be non-trivial to implement.

I don't understand what you mean, because it doesn't apply the background colour to the rect. It shows as white on red. Red is the foreground colour: the surrounding text is red. This is exactly the same as the first case where the rect is filled with black because black is the foreground colour. If you believe Emacs should behave differently then I don't see any reason why we can't change it, as long as it still allows the use of SVGs inline as widgets or icons, etc. without forcing the programmer to explicitly handle changes to colours when faces change, or the mouse hovers over the line, etc. I'm not an expert in SVG, so it's quite possible there's a better way of doing this that I don't know. If someone does have a proposal I'd suggest it should probably be made in emacs-devel, because it will be a change to behaviour that will likely interest anyone who already uses SVGs, and please Cc me in as I don't read emacs-devel regularly. -- Alan Third

It indeed explicitly draws a rectangle over the page, effectively inverting background and foreground (Emacs has no reason to apply background color to the rect object fill).

The image draws a rectangle in the current foreground colour, black in
the first case and red in the second, and then fills the text with
"#fff".

IMO users should be able to change this behavior, so that emacs can be compatible with svg images that don't set the #000000 color explicitly. I don't understand why you say this. Emacs behaves with SVG images as it does with text: the colors of the face override the default colors. IOW, it's a feature, not a bug. As Alan says, images that want to display specific colors should specify that in the image spec.

This behaviour is documented in the elisp manual under "SVG Images" and is intended to make it easier to insert images into buffers so they look like native widgets and the like. We only set the default foreground and background colours, we don't override explicitly set colours. The easiest work-around for someone generating an SVG for display in Emacs is to just not set foreground and background colours at all, and then they'll both match the current theme (and also work correctly in web browsers). (IMHO if an SVG needs a specific colour, like the black in the German flag above, it should be setting the colour explicitly, rather than relying on the image viewer's default settings.) -- Alan Third

The LaTeX preview is displayed as a white rectangle. > > After debugging, I found that it is because dvisvgm omitts the default #000 color value when generating SVG file, and emacs has a unique way of displaying the SVG, which caused foreground color to be applied to it. > > A solution is to change org-format-latex-options to use transparent background by default. I've attached this fix. It turned out that emacs displays svg images differently compared to an image viewer. I can reduplicate this issue when I use emacs to view this svg image, which emacs replaces the image's black color with the current theme's foreground color: https://commons.wikimedia.org/wiki/File:Flag_of_the_German_Democratic_Republic.svg See also (Chinese): https://emacs-china.org/t/emacs-30-1-svg/29217
