Another variant: You could also render the original (black) SVG element to a temporary QImage, then use pixel manipulation to colorize it to red, and then render that image to the main painter.

Really, what you should do it what he describes, but render it to a PNG/Pixmap, and store that.

SVG is xml. Just load it into a QDomDocument and change the colour.
If the SVG does not change too much, you could even do a search and
replace of the color values. There are many ways to achieve what you
want, forcing the QPainter to use a certain colour when rendering a SVG
image... I am not so sure about that.
Btw... SVG isn't the most resource friendly format.
