A lot of designers I know just keep a raw layered image and swap out themeing on a per-case basis. SVGs are easier to dynamically theme, but usually any theme variants get run by a designer anyways that will tweak color tones for the specific usage as needed. Just to be clear though - I love SVGs and want them to get more momentum solely on the basis that they're just a way better way to store abstract line art and can yield proper image scaling... I just think a lot of the technical advantages we tend to think of aren't really that valued by designers and get lost in needing to be done manually anyways.
