When I do this before and after this patch:
$ make qemu_arm_versatile_defconfig
$ make graph-depends
The color for "rootfs-common" and "rootfs-ext2" changes.
Can you reproduce it?
Is this intended?
If not intended, do we care enough?

Why not the straightforward version?
        if pkg_list[pkg]["type"] == "rootfs":
            versions[pkg] = None
        elif pkg_list[pkg]["virtual"]:
            versions[pkg] = "virtual"
            versions[pkg] = pkg_list[pkg]["version"]
