Background color in SVG display

[Pascal Quesseveur]

Hello,

The way SVG files are displayed has changed with emacs 28: the
background is now displayed with a color that looks like coral4. Where
does this color come form and how to change it?

I use Windows compiled binaries from GNU.

system-configuration is "x86_64-w64-mingw32"

system-configuration-options is "--with-modules --without-dbus
--with-native-compilation --without-compress-install CFLAGS=-O2"

system-configuration-features is "ACL GIF GMP GNUTLS HARFBUZZ JPEG
JSON LCMS2 LIBXML2 MODULES NATIVE_COMP NOTIFY W32NOTIFY PDUMPER PNG
RSVG SOUND THREADS TIFF TOOLKIT_SCROLL_BARS XPM ZLIB"
