The separator should definitely not be a space. Spaces are less separating than commas (think of natural language) so it looks like the first two colors are grouped together and separated from the first.

I'd support a keyword if there was a natural fit, but that doesn't seem to be the case, and unnatural keywords are suboptimal. Not sure about combining slashes and commas either, I can't think of any precedent and I think for most people their relative precedence is undefined.

There is precedent here for commas: In gradients, the gradient parameters are comma-separated from the color stop list, even though they are not part of the alternatives listed. I'd vote to just go with that here too.
