[QGIS-Developer] SVG toolbar icons suddenly appearing in black

[Charles Dixon-Paver]

Hi Raymond,

I am on Windows with 3.20 and the icons are blue for me.

I opened the SVG in inkscape and saved an "optimized svg", which runs
scours against it, and all that changed is the <?xml version="1.0"
encoding="UTF-8"?> definition was added and version="1.1" was injected into
the svg tag.

One oddity though, is that when I changed the feature colour and saved it,
the "bright" svg version retained the <style>.a {fill: #1b3d6e;}</style>
data element, but the *path* tag got a fill="#00f" added into it. I imagine
QGIS is recognising the CSS (for me) but giving preference to the fill
attribute.

Still, all icons are blue for me...

It could also be a contrast issue on the users screens changing, where the
blue icon is simply appearing black, but I imagine most likely the system
is not recognizing that css style in the svg.

I hope that helps you.
