I would like to suggest the following, feel free to close if you don't want to follow this path.
<text
class="normal_label"
inkscape:label="text125"
fill="#bfbfbf"
font-family="Calibri, Calibri_MSFontService, sans-serif"
font-weight="400"
font-size="24px"
transform="translate(838.371,658)"
id="text125">Type</text>
rsvg-convert -f pdf rust-memory-container-cs.svg > normal.pdf
will generate PDF as in SVG. So it will look like this

But CSS will allow to change attributes based on selectors, such as classes. So if red_labels.css
looks like
rsvg-convert -f pdf -s red_labels.css rust-memory-container-cs.svg > styled.pdf
