Doesn't support colors with Adobe's (or any, idk) CMS in SVG
I know no better way to phrase the title, as I barely understand this myself. Basically, when opening an SVG which elements have their color selected with "CMS" of value "Adobe-RGB-1998", they will render colorless in Loupe.
But when you open Inkscape and change the value of CMS to "none", it jumps you to "HSL", and everything's fine thereafter.
You can test this by downloading an archive with this image, opening the .ai
file in the archive with Inkscape, and saving it as SVG.
