Using Semi Permanent Hair Dye?

I have like a wheat blonde hair and I want to dye it a dark brown, but eventually want my natural blonde hair with highlights back. If I use a semi permanent hair dye will it eventually come back or will my natural highlights be gone? I don't want them to be gone forever, but I wanna go dark brown for a bit, but I'm scared that the semi permanent dye will change my natural coloring?
