I favour a solution that is implemented as some sort of system
extension. Since we are dealing with a single resource (a palette) a
single program should manage this resource. It has the added benefit
that programs that are no longer updated will be able to use newer
versions of the colour manager. And it would also be possible for
programs to 'upgrade' that part of the OS, instead of requiring the user
to upgrade to at least TOS 2.06 or something like that.

But a program could do a request for a colour within a certain margin
from some value.
